Keeping an open mind is the most important thing. Keep your eyes and your ears at open at all times. You never know what you could miss out on. Never underestimate anyone's ability or talent. Looks are EXTREMELY deceiving.
The ones who you think won't do their thing will be the ones who make the most noise.
And the ones who you think will tear shit down be wack as hell. Don't sleep.
Never judge a book by its cover...
