Do not let the opinions of others (or, more accurately, what you think their opinions MIGHT BE), stop you from dreaming big and being true to yourself. We are all “weird” in one way or another. We’re all unique.
Stop trying to be like everyone else. The average American is overweight, in debt, and doesn’t like their job (life?)…why would you strive to be more like that?
Be true to yourself. Dream big, but more importantly, go after those dreams everyday. People may say that what’s you’re aiming for isn’t possible. But those people either don’t understand the dream, don’t understand the effort you’re willing to put in to make it happen, or don’t want you to succeed because it will make them feel worse about themselves. They’ll eventually come around when you start achieving success, and if they don’t, don’t worry about it. You can only control yourself – your thoughts/beliefs, actions/inactions, attitude, etc.
