Chris Hadfield, quoted at Zen Pencils:

“Decide 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.”

Start sculpting yourself. A slow, purposeful process. Shaping, trimming, removing excess. I like that.
