Like everyone else, I've struggled with "being myself" quite a bit. But recently I've found a little thing I do with myself that helps me "be myself".
True, I don't yet know who "myself" is. Throughout your entire life you develop your identity. It's nearly impossible to know exactly who you are. But I found a way for me to get much better at being myself.
The shortest way to put it: relax. Don't try to be anyone in particular. Don't try to be cool. If you just relax and let yourself be you - I think that's key: letting yourself be you - then "you" is going to show up!
Let's say you're talking to a really nice group of girls who you've never met before. Part of you wants to come off as a cool, popular person. The other part wants them to see "you", even if you're not sure who that is quite yet. If you just relax and let yourself do what your personality tends to naturally want to do, you'll be giving people a glimpse of the real you.
I admit, it can be harder said than done. It's hard to explain, probably hard to understand...yeah. Pretty much. And there's a line you can cross. I keep wanting to say "Don't monitor what you say," meaning "Don't try to say things to make you sound a specific way." But there's a line you can cross. For example, if you're in the habit of cursing in every sentence, even if what you're saying gives the real impression of you, the cursing will distract people. Don't monitor what you say, but up to a point. There's a balance.
I congragulate you if you read through all of that rambling.
I congragulate and applaud you if you actually understood what I was trying to say! :P
