“Decide in your heart of hearts what really excites and challenges you, and start moving your life in that direction. Every decision you make, from what you eat to what you do with your time tonight, turns you into who you are tomorrow, and the day after that. Look at who you want to be, and start sculpting yourself into that person. You may not get exactly where you thought you'd be, but you will be doing things that suit you in a profession you believe in. Don't let life randomly kick you into the adult you don't want to become.”
― Chris Hadfield

“To me, it’s simple: if you’ve got the time, use it to get ready. What else could you possibly have to do that’s more important? Yes, maybe you’ll learn how to do a few things you’ll never wind up actually needing to do, but that’s a much better problem to have than needing to do something and having no clue where to start.”
