To improve, you must make your weaknesses your strengths.
Personal sacrifices are really the beginning of the end of everything because you don't win because you do one thing or two things right. You win because you do one thousand little things right throughout the year.
The only discipline that lasts is self-discipline.
Champions keep playing until they get it right.
Win with class, lose with class, and always respect your opponent.
Always have a plan, and believe in it. Nothing good happens by accident.
