I talked a while ago about being cautiously optimistic. I now consider that to be an oxymoron... you can NOT be optimistic while being cautious. You have to just jump in to what ever it is with both feet and let things fall as they may. If things don't turn out the way you hoped, you have to accept them the way that they are, however they are.
Embrace life fully. Live life for what it is, a journey.
Be good to yourself!
