How was it put to me, anger, frustration, resentment, envy, all those dark emotions we sometimes feel are basically like drinking poison and expecting the other person to die - they serve no purpose other than to make us unhappy.
I try to be grateful everyday for what is in my life, whether good or bad, I know I'm supposed to be right where I am today, right now, doing what I'm supposed to be doing, so I try to live in that and experience it to my best, by doing my best to participate in the lives of others, because none of us is promised tomorrow...
MisterMoo - well put, all the best to you...
