My most frequent example of procrastination is in assignments I have to do, especially when I was a student. I would wait till the last minute, when I had no choice but to just do it. Then, I expend so much energy, trying to get it done quick, when I could have done it much easily earlier.

The last minute thing works for some though, but that's not a license for procrastination. Thanks @jeffways, thanks @adsactly
