The manner in which your ego responds can play a big role in this transit.  If you become too big for your britches, so to speak, or allow success to go to your head, chances are it could come back around to bite you.  There is a tendency with Jupiter to try and do all the things, and this can lead to your downfall.  At the moment, focus on the best projects you have going, and work to bring them to fruition, before trying to take on more than you can handle.  The positive feelings you may be having here will increase your confidence, but one must be careful not to become overly confident.  Be thankful for your successes, and give credit where credit is due.
