I believe most people in the world are capable of being creative individuals, but there are some things holding us back from letting the creativity flow. I don't expect the guy with a freezer in his garage that's full of deer meat to be writing movie scripts or doing stand-up, but it can be done. Some people are just born without creativity, and those people are probably way better at building a house or being a farmer better than creative people. That's just the way the world is. Nothing wrong with that... BUT there are people that know they're very creative, but have internal things that are holding them back, and if you're one of those people, maybe this will help.
IF you have dreams of becoming something that you know you are capable of doing, but there's something holding you back, you got to let that shit go. One of those things is likely self-judgement. Why judge yourself, when you don't know exactly what others are even saying or thinking? If you like to fart in your bag of chips when you open them, do it. Who cares. You got to let the brain open to a level that you haven't achieved before in order to do the things you want to do. Scared? Why? What's the worst that can happen? If you see a woman or a man that you find attractive but you're too afraid to go up and spark up a conversation, you have to act like you're the one that bitch slapped Bin Laden down to Satan's rape dungeon and gather that courage up like a cute little squirrel gathering acorns.
WHEN you feel embarrassed about being outgoing or, lets say silly... just the next time you feel the urge to do the robot, do the fucking robot. OWN THAT SILLY DANCE. The world is full of people that'll point their dicks at you and judge judge judge, but you got to own up to it you know? Typically, when someone goes out of their way to be fun and outgoing, that's just a sign of a selfless person. The world needs less "bros" ordering shots of ridiculously expensive alcohol to impress an individual, and more people that'll go out of their way to bring laughter and a smile to one's life. So, the guy wearing a scarf and capri pants is giving you a dirty look... tell him that you got a large amount of diarrhea in your pants and you're willing to part ways with it via his face.
Point is; just stop judging yourself and quit worrying about what others may think or say about you. It really all comes down to one's ego. Typically, when someone has a massive ego, they're terrible people. Tell Mr. EgoBalls to lighten up and take a swig of creativity jizz.
