No matter what you do today, do it with conviction. Now is not the time to be wishy-washy, or to drop something once it starts to get boring. Today you have to commit. Save the flighty behavior for another time, when no one is counting on you and you have the freedom to flit from one thing to another. If you are too unpredictable now, you run the risk of confusing people who need to have confidence in you. Even if you have to fake your conviction, do it.
