If you decide to be a Jedi, you should be a Jedi all the time. It is not as if being a Jedi as a separate identity, like you have two personalities- who you normally are and who you are as a Jedi. This is like trying to function with only one side of your body or the other. In doing so you make half of yourself oppose the other half, when you should be integrating both halves. You are not you as yourself, or you as a Jedi. You are both. You need to unify yourself and your efforts. Certainly there will be times when one aspect of your being would work better then the other in a situation. But you have to be able to use both sides if you plan to succeed in all things.
