What works for you? Please share.
A couple of other things I have learned are:
1. Don't multi-task. (Because it reduces your productivity.) Instead concentrate on one thing at a time ― unless multi-tasking is working for you. 2. Work in clean allotted amounts of time. (Something like 1 - 1.5 hours or whatever works for you.)
And 3. Take "clean breaks". Which basically means completely "unplugging" from what you're working on for 15 minutes or so.
