Practice your craft.
What may just be a hobby now could one day be something very special. If you love it, practice it.
Don’t be that 40-year-old guy who says to every young person he or she meets, “I used to want to be a guitar player!”
Well, why aren’t you still playing then?!
Wake up when you say you’re going to wake up.
When you set that alarm the night before, you’re promising yourself you’re going to get up at that time.
Keep that promise.
