Its tough to be an optimist. I have to work at it. If I'm not careful the hum-drum, doom-n-gloom around me can, and sometimes does, bring me down. I have never really been a pessimist. I have wallowed in pessimism before, but never really made a home there, I discovered that being a pessimist takes too much energy. I have to work at it. Being a optimist is so much easier, takes less energy, and is more fun.
Sometimes, I think people look at my optimism as being lazy, or they think that, in reality, I don't care. Those are both fallacies. I do in fact care and I'm not lazy. The last few weeks on the job front were tough for me, but I kept telling myself that there was a reason for all the things that didn't go my way. I believe that wholeheartedly. I'm sure that I'll look back on the last months in the future and say "yep, that's why such and such didn't happen. Thank God for that..."
