Alright /fit/ I need some advice, 5 years ago I used to be 250lbs

I was never a fatass but I was pretty much entirely ignored during high school, I think there was even an entire school year where I didn't have any friends - not even bullied or anything, just entirely alone.
I'd shake and even have some mild stutter when I talked to girls. Later on served a couple of tours and when I got back no one even remotely remembered me.

So, when I had no one to impress or disappoint but myself I could do things that some people simply don't have the freedom to - and that's things I genuinely liked and wanted to do -
Fishing, hiking, reading all those books you always made a mental note to read but never did, watching movies, learning history, volunteering with wildlife, learning finance, learning to play instruments, learning languages, car maintenance, lifting, going to places your friends never want to go to - every hobby and activity I picked up eventually taught me something about myself and in some way completed me.

I met people through my hobbies and the places I spent time in eventually it snowballed into people just wanting to spend time with me because eventually everyone wants to do fun new things.

I guess to sum it up, live for yourself, invest in yourself, enjoy your life - people will eventually flock to you but what you would've earned way before that happens is the realization that your happiness doesn't lie in other people, that's projection, only you can make yourself happy.

Sorry for the gay zen shit but I hope it somehow clicks.
