That’s a hard question . There’s billions of people with different interests. For me I’d say my self worth is tied to my wife, and family. I try to be the best person I can to make her happy and I’m always there for my family and friends to help with whatever they need. As long as I’m worth something to someone I’m cool. I live by 2 simple rules. 1)Don’t be an asshole. Anything that you do, ask yourself “am I being an asshole by doing or saying this thing?” 2)Don’t worry about things you cannot control. As long as you know you’ve done all you can, there’s no sense in worrying about the rest. The danger of tying your self worth to one thing is if that thing doesn’t work out, you’ll be super hard on yourself and just beat yourself up. Or if someone attacks the thing you love, you’ll take it super personal because your identity is tied into that thing. It’s as if they are attacking the thing that makes you, you. IMO this is what’s wrong with being a super fan of anything. It’s ok to love something but don’t make it your whole identity. I love Lego, would I ever get insulted if someone said something bad about Lego or being an adult Lego collector? No, because it’s not who I am it’s just a hobby. I don’t derive my self worth from it. I hope this makes sense. And again I am actually very jealous of you. I WISH I cared about my body enough to really go hard on working out. I just don’t have that drive inside me to put in the hard work. I use to train when I was younger so I know how hard it is.
