Quandry

Since graduating, I've been faced with many potentially life-altering decisions.  Where to live.  What to do.  And when to move forward with any of it.  What for some may have been an easy task, I have found the answers to these questions quite daunting.  And, just when I feel like I've finally made a break through, come to a decision, and I feel REALLY good about it, for days or weeks at a time even, then a new day comes, and the choice seems to weigh heavily on me.  Is it simply discouragement creeping in?  Is it just me, overanalyzing the situation?  Is it my brain fully comprehending all of the implications of such a decision?  Or is it simply because it's not the BEST choice for me right now?
