My thoughts:
In life, we're constantly working towards something. Long term goals, short term goals, daily goals.
And with the big goals, the whole time we focus on how perfect everything will be once we reach that big important goal. When we have, we then realize getting there was half the fun.
Then we need another goal right away.
With daily goals, such as we set out to make a certain amount of money, and have a blast getting there.
Then we over exceed the quota for the day, but then it's quiet and the pain of life sets in. When we should be happy.
My take it on it anyway. I worry a lot, so it doesn't matter how perfect everything is, I still find something to obsess over and ruin everything.
