Watch your thoughts. They turn into words, then turn into actions.
Think good, speak good, and be good.
If there's a field you're interested in, do some research. If you can, go to school and study it to really understand it from its core.
Sometimes, I need to be high off the ground to keep grounded.
Watch who you have around you, and focus, work hard, and be humble, and try to be good.
Make sure you surround yourself with positive people that will support you and push you forward and won't drag you down or get in your way.
