The best dating advice I could ever give is:
If someone thinks you're hot the first thing out of your mouth, on an app DOES NOT MATTER. You can literally say "Hello, I'm ___ nice to meet you." If they think you're hot they will keep talking to you. If they do not, it doesn't matter what you say.
Why is this good advice? Incels say you should looksmax so that everyone thinks you're hot, but that's the stupidest advice ever. Women are constantly asked about who they think is hot by RESEARCHERS and the answer is the same every time: It depends. Men tend to cluster around the same type of women a bit more, but I'd argue that it depends for them too.
The reality is that someone, somewhere will find you hot, without any changes to your looks or personality.
Your goal isn't to craft the perfect message, make the perfect profile, wear the perfect clothes, do pushups, get surgery. If you do that you'll actually become MORE insecure because you're constantly obsessing about how awful you look. And that will make it harder to find love because you will be more hesitant to be yourself in public around people who would like that.
If you do the above, what you're actually doing is trying to fend off rejection, instead of chasing success. Because you can't date everyone. It's not physically possible. And ironically, no matter how much work you do on yourself, TONS of people still won't like you, not because you failed, but because they just like different things. Instead of seeing that for what it is, the world being a big and diverse place, you will internalize it as a personal failure and you'll be like that weird monk in The Davinci code who beats himself with a mace in private because he was a bad bad boy.
Your goal is to literally just go out into the world, be proud of who you are, and do stuff you like. You will run into someone who likes the same things and likes you and thinks you're hot. And... if you're okay with being rejected by a lot of people romantically, you just see it as you're not their cup of tea, you will be proud of yourself, outgoing, and you'll find someone who is like "holy shit where have you been my whole life."
And you didn't do one situp. You didn't learn a new makeup routine. You didn't buy a cool car.
You just said, hey maybe I am actually hot and cool. Maybe people do like me. Maybe I'm fine the way I am.
And someone else out there said, no you're not just fine, you're amazing I want to date you.
Stop overthinking your dating profile. That's the moral of the story.
