text: Because that is what life is about! Keeping us on our toes....keeping us alert......presenting challenge after challenge so that we never become stagnated and always strive to improve......to grow. If life were predictable, wouldn't we all be so bored. If we knew what was around each corner would we not turn around and go back? Sure.....we get to piss and moan about "Why didn't someone tell me this could happen???" But deep down inside, the pride from overcoming the obstacle outweighs the obstacle.Great question. :)
