I want to be like you when I grow up.
DD’s GUIDE TO GROWING UP LIKE HER
Have a weird origin story. If possible, be born to a nameless single mother and adopted (as a baby) from a foundling hospital by lower-middle class suburbanites.
(Also: start reading as early as possible. Extra points if no one remembers teaching you how.)
As a young child, have long conversations with imaginary friends. Start having similar conversations with media characters ASAP. (For example: a long discussion with the 1960s Mighty Mouse, which causes one of your parents, alarmed, to send you for psychiatric evaluation.) Continue these conversations into at least your mid-seventies.
Watch many cartoons. ALL THE CARTOONS. (And be unbelievably fortunate in having this phase occur during the golden age of Warner Bros. animation, so that buried deep in your ground-of-being are the classic Road Runner vs. Wile E. Coyote cartoons, as is "What's Opera, Doc?".)
Be initially seriously freaked out by monster movies (i.e. the original 1954 Godzilla) until multiple viewings of one of the more ridiculous ones start to make you find them funny.* Thereafter, love them all desperately. And routinely, later, be inevitably on the monster's side.
Decide that you want to write a book. Write your first one at age eight, in crayon (and also draw the cover, because you think that novelists have to do that). Have serious concern about your inability to write as small as real writers seem able to do for their printed books. ...Keep writing anyway.
Survive elementary school (even though it's boring). Survive secondary school (still boring). Survive high school (ditto). Keep writing.
Have severe teenage crushes on select boy bands until you find a more suitable mass media personage to have a crush on. Get a haircut like his if you can talk your mom into it. Keep writing.
Spend at least one of your teenage years practicing how to put up just one eyebrow the way that character does (thereby permanently changing the shape of your face). Fascinated by that character, start writing your own stories about him, thereby inventing fanfic without knowing that (a) it had already been invented or (b) that it even had a name.
Write truly forgettable Star Trek/Monkees fusion fic. Burn it (mercifully) before anyone sees it. Then, more than half a century later, admit to its existence regardless, thereby possibly identifying yourself as some kind of masochist.
Put off career-choice issues as long as possible due to having realized that no career choice your high school recommends for you seems even vaguely sane. Find a friendly local college that will let you major in astrophysics, as astronomy is the only thing that interests you as much as reading science fiction, fantasy and fairy tales. Go to that college and (somehow) continue writing: Tolkien fanfic, this time.
While studying astrophysics, flunk calculus. Realize that this is probably a dealbreaker, and—after some thought—change streams, using the other half of your science-and-nursing scholarship (which is the only way you could ever have afforded to go to college at all) to go to nursing school instead. Meanwhile, start writing some strange kind of non-fanfic fiction about original characters in a medieval-flavored landscape with unexpected cultural add-ons that would doubtless make Tolkien shake his head in extreme bemusement.
Graduate nursing school. Continue writing while working in (at first) a truly dystopian psychiatric-hospital setting, and then (within a matter of months) in the most prestigious psychiatric clinic on the US's East Coast. Discover (in passing) that your colleagues do not consider your fiction anything to be concerned about in the professional sense, and are definitely absolutely unconcerned with any conversation you might ever have "had" with Mighty Mouse.
Meet a Star Trek writer at an early Trek convention. After becoming friends with him, eventually burn out on your clinic job and (at something of a loose end) go to work part time for your friend as his assistant. While doing that work, realize, to your utter shock, that it is apparently possible to actually make money doing the kind of writing you've spent a significant portion of your life so far doing for free. (An option that honest to God[dess] has never previously occurred to you until you see it happening in front of you every day.)
Emboldened by this realization, finish writing a book containing your non-fanfic characters and show it to your friend. To your complete shock, have it sell to an actual publisher a few weeks later. Have the book be nominated for awards within the year. Don't worry about winning them. Worry more about what the hell you should do next.
Figure out that the thing to do next is is write another book. (Which sells.) And another. And another.
Keep telling stories. Keep writing. Keep selling (even if sometimes circumstances require you to do this yourself). Never turn down offered work, especially in films and TV. (Specifically, when a story editor hunts you down after reading your first book and asks if you want to write cartoons, SAY YES for fuck's sake. Over time this will cause you significant aggro from badly-behaved directors and misogynistic production staff, but it will also be a source of great joy.)
Keep doing your work whatever continent you happen to be on, and meet many extraordinary people in the process. When you realize that one of these people whom you've run into is your soulmate—or you're his—snatch him as quickly as possible off the dating market and marry him before anybody else starts getting cute ideas on the subject.** Live many happy years with him, in which every day is an adventure. (Noting here that it really helps if he does the same kind of work you do. As Gandalf says, this "saves the long explanations needed" for so-called Normal People.)
Never give up your fandoms, no matter how old. Never be afraid to acquire new ones. (Because those fusion fics have to come from somewhere...) Keep working to find your joy. There's always more you haven't found yet.
Rinse. Repeat. Tell stories. Keep talking to people who aren't there (until you cause them to be, which you will discover is a full-time job, but one in which persistence pays off). Don't stop until you decide to give up breathing.
...And keep working that eyebrow. 😏
Anyway: that's what I've got on the subject so far. Do let me know how your project of Growing Up Like This turns out.
(And BTW, just so you know: the "growing up" part is optional.)
*It would be tempting to attribute this film to being the cause for your long fascination with Switzerland, but data to support this conclusion remains thin on the ground.
**NB: biological sex, gender, pronouns and and preferences of your soulmate may vary from any or all of your early expectations. Don't let that bother you. When you recognize the One, don't waste your chance.
(Side note to @radioactivepigeons: Got no advice for you, alas. I too can only do one side [the left]. When I try to do the right by itself, my facial muscles just laugh at me. This is, to put it gently, mortifying, so I've stopped trying. Maybe one side is meant to be enough.) 😅
