Enthusiasm is a very good thing, but, if you don't point it in the right direction, it will torpedo your fresh starts.  Here's a for instance.  Say your fresh start is to paint again, for the first time in years.  If you're not careful, you'll only have your eye on the finish line -- the ta-dah of hanging the finished painting over the fireplace.  There are two problems with that.  First, if you're only looking at the finish line, you may well never get there.  Second, even if you do, you'll have missed all the ta-dahs in between, and that's where the joy is.  The joy is in the process -- in driving to the art supply store and in deciding what to paint and in the surprises and even in the do-overs.  And the deepest joy comes when you remember that the process is more than just you alone with your painting.  It's you in the good company of the One who gives you the desire to paint and the eyes to see the canvas and the energy to pick up the brush.  It's the deeper magic of "I" becoming "we."  It happens day by day, step by small, faithful step, and it takes all the pressure off the final product.  The deeper magic let's you relax and forget the finish line and enjoy every ta-dah moment along the way.
