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.
Watch your thoughts. They turn into words, then turn into actions.
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.
I hike a lot. The view and the air up in the hills are much greater than the hustle and bustle of the city. It makes it all look so silly and small.
