I have a small cluster of things I'm passionate about.
Some things I'm more passionate about than I am about others. I'm more passionate about my art and writing than band, but I'm still quite passionate about anything to do with the band, trumpet, or marching band.
My biggest passion, though, is making people feel loved, or at least making them smile.
And that's valid. It's not very specific. It's not something I'm going to make a career of. That doesn't make it any less important or fulfilling to me. It's a simple thing. I love making other people's days a little bit better. I love making an impact, even if a small one. I love giving my friends affection and support, and reminding even strangers that they are loved, that even if nobody can help them up at the moment, they can help themselves, find some joy in the little things. Just a simple smile, "Have a wonderful day," can make someone's day. Anyway, I'm rambling. What I'm really trying to say is
Your passion is valid, no matter how small or silly it seems. If it brings joy, keep doing it.
