You will always emerge
stronger from your challenges.  Yes, you
may feel as if you descend to the depths of despair, but from the firm bottom
you bounce back even higher.  If you
always stay on even ground, there is little growth.  It is by experiencing diversity that you
learn.  Learning and growth are why you
are having this earthly experience.  Be
aware:  There is a difference between
experiencing what you perceive as challenges (the lows) and experiencing
massive mood swings.  The two need not go
hand in hand.  Indeed, when you can
separate the two, then you know that true growth has occurred.
