If I were to agree with the sentiments in the cards and other birthday related markers shared with me over the past (more than I care to state) years,  I would clearly believe I was already 'over the hill'!  Today I feel the strain of the climb, so how could I be OVER that HILL already?!  How long will this climb continue to challenge me?!  Perhaps until I realize I can always let go, slide on down the hill and set myself free!  Hmm...can it really be that simple?!
