Just remember that learned intelligence doesn't always equate to court wisdom. You need both to be a great player. The great players have the ability to make just the right judgments on the court at the critical time. Judgment knows the more prudent of two paths in the road even if the road you take looks like it has a steep hill at the onset. You can never learn too much as a player.
Great players have a wealth of knowledge about the game and go the mental library often.
However, you must never accept them as personal limits. Great players never accept the level they are presently at as a player or person, or limit where they can reach, regardless of what others say. Learn how you are special and unique as a person and player and play that music. In other words, strive to fulfill your full potential with the gifts you have been given, and play that music. All of your teammates, coaches, athletic trainers, managers, fans, etc can help you succeed OR fail.
