play with your mind

Open minded people are nice people. They're not judgemental, they make you feel confortable, they know lots of stuff but they don't brag about it, they're always eager to learn more, they're fun, they're helpful, they're fearless, they do stuff that matter to them, they get things done, they get things changed and basically they...just get it.

Here's something to exercise an opend mind.
But beware: one hour of increased brain activity via thinking a lot or experiencing new stimuli can make you smarter, more energic, more creative and more sociable.
