If you are in a hurry to get to an appointment, and you are riding on a train that is moving too slow, do you think you will arrive at your destination any faster by getting up and running through the train?  Likewise, when the time is right for you, you'll be arriving at your destination ~ no sooner, no later.  In the meantime, make sure you are on board.
