This makes a good basketball quote but a great Navy SEAL and leadership quote. You can't reach targets unless you have commitment, discipline, and goals.
I can't force players to practice hard, to communicate, to use 'better' technique. They have to want to improve, to follow, to do more to become more. But we can lead positively and urgently.
Today, a colleague told me she can't work out because she has knee pain. My response was that you can't do the SAME workout with knee pain. She can swim and do circuit training or free weight exercises that don't stress those joints. While you recover "don't let the things you cannot do interfere with what you can do." I gave her a small piece of tape with the words, "I can do that" written on the tape.
