For me, its all about each day. I have a failing in thinking too much about the future so that I can't enjoy the present. Don't have much of a problem with the past. Sure I stayed a dub too long, but it wasn't wholly bad. No its too much living in the future that is my bane and at 60 there is not as much future to obsess on.
I try to enjoy the good things of each day. Of course, there are the rare perfect days and the rare perfectly shitty days, but mostly its a mix. Right now the roses, iris and peonies are blooming gloriously. The bay magnolia puts a sweet odor on the whole yard not to speak of the honey suckle. The dog is asleep by my feet. I am well fed and enjoying a glass of rum before bed. Its a good day.
You know if you string together enough good days, you may come up with a good life.
