Having a couple of things I like to do helps me such as listening to music, reading, watching movies, gaming etc. Having the discipline to cut off took a while to master as well. Over the weekends, I tell my team members not to send emails or text messages unless its super urgent. I give myself targets, for example watching a couple of movies or TV shows over the weekend and deal with the shit come Monday.

I was supposed to have a great time but instead I burned myself out

That's when you need to take a step back, do something else. When I'm gaming I do burn myself out, so now I'm taking a break from WoW and started on movies / tv shows again.
