Hi, Hero, welcome to PsychCentral (PC).

I don't know if what you are suffering is an OCD issue or something else. I would make an appointment with a therapist and explore your feelings about it if it bothers you.

One thing that caught my attention is that you seem to be comparing yourself, an individual, against a mythical "other guys" group. There's no way you can ever compete with a group, especially a group that doesn't really exist, is whatever a writer decides to write. You might as well compare yourself to James Bond or one of the heros in the TV show "Heros"?

I think you should make a list of behaviors you would like to have and work toward learning them. Or, decide on a lifestyle you would like and work toward that. Comparing yourself against something in the past is not helpful since it is like trying to drive a boat based on its wake? You cannot know if you had as much/less/more fun than imaginary other guys, 3 years ago in college because there's no such target and what we remember of our own experience isn't always reliable as "fact" and we didn't know the imaginary other people and their experience at all!

Decide what you would like in the future, reduce it to detail and plan it out and do it for yourself; to heck with those unbeatable other guys that don't exist! There's always people younger and older, smarter and dumber, more experienced in X or less experienced in X, etc. To heck with moving targets, find a stationary one you want and go get it.
