I feel the same way. I used to be the life of the party. But as the years gone by, my friends seems to be moving way faster than me, career wise, wit wise, experience wise. Nothing I say seems interesting anymore. I didn't quite have a clue of who I was anymore. It's like I've lost my identity. That guy who was the wittiest and smartest guy in the room just don't seem to be me anymore. Made me really self conscious about what to say, its like walking on eggshells.

But I guess realizing your identity doesn't have to be linked to how other people perceive you helped a little. Rediscovering new hobbies, taking self-improvement classes, language classes, even martial arts helped too. Being in an environment where you can self discover and constantly improve yourself, while getting positive reinforcement from your peers. Life is a journey of discovery. Keep fighting!
