Biggest Pet Peeve

I think I’ve just discovered something interesting. Everthing that drives me crazy is rooted in the same principle: I HATE HAVING MY TIME WASTED. Everything that frustrates me is based on that. It’s why I hate 2 hour meetings where nothing new is revealed or accomplished. It’s why I hate when anything goes longer than promised. I have to pack so many things into my walking hours that I dont have the margin to accommodate others who dont respect time.

So, if I can’t control others, and I can’t control my schedule, I have to change my attitude so that I’m not angry all time. Any suggestions? How can I adjust my perspective?
