Have you ever had a project you looked forward to completing, got everything together to work on it, rubbed your hands in in anticipation, then spent the next two hours in frustration because it JUST WILL NOT WORK?
I hate wasting time. The older I get the more I realize I probably have less time left than I've spent on this planet. Scary thought! And to spend time and get nothing out of it irks me more than many things. Including burnt toast, which only wastes a few minutes of time and a cheap piece of bread.
Then I get all philosophical about what wasting time teaches me. All the positives. Yeah, right. Wasting time is pointless, fruitless, and boring. All it teaches me is that I should have planned my project better. Done more research. Left open other possibilities instead of burning bridges so at the end I'm not left with nothing.
