I disagree with one thing said. There is a difference between being committed to something and becoming obsessed with something. I am a firm believer that what separates someone from becoming the absolute most crafted in their field and someone who knows it well enough, is obsession. I am committed to a lot of things in life. Some of the commitments I have I necessarily don't even care for. When I become obsessed with something, I take it to that next level. I am constantly studying, practicing, or whatever else it takes for me to be the absolute best at whatever it is.
