A day turned around

I thought I was having a bad day today. I was tired. That used to be OK, but now it makes me nervous because I think it means a lack of oxygen. I walked to the mailbox anyway, but was still feeling sorry for myself until I read an email from on old friend. He congratulated me on the exercising I'm doing and that I'm raising my O2 level. And I am. I just forgot that today, I suppose. It's that instant gratification thing. I want to feel fabulous all the time. I don't know why - I never have and I doubt that anyone feels great all the time. I just wanted to enjoy this summer. I love to swim and had even thought I might make a trip to the beach. And who knows? I might. I do know, however, I will swim and swim and swim and if I get tired, so what!
