Yeah, ozzy, I am fully with you, and I think I know a little about what you wrote myself.
Fact is, I notice that just thinking "oh fuck it let's go bowling" when I feel I get uptight about some thing or the other helps me to stay cool, give a shrug and ... oh well..have it your way.

So, no it is no waste of time at all, it helps to become more relaxed, which can't be a bad thing.
Faithfully
