One of my most important insights of the last years: Procrastination is cheating yourself. To procrastinate means that you waste your time in every way. You don't use it to do the things that need to be done, nor do you use it to properly relax and gather your strength. The truly worst form of procrastination, however, is pseudo-work. You may know the phenomenon: often you find yourself in a situation where you can't find the strength to pursue a thing effectively and instead you settle for minimally dealing with it in some way.
The time I take to work, I want to make as effective as possible. I therefore avoid surfing the web or writing messages on my smartphone at the same time. Instead, I try to jump right into the work process and generate a flow that carries me quite a bit through my tasks. But I have many different projects going on at the same time, and I've often found myself unable to choose one to keep working on, despite having so many projects. It was a bit like the forest you can't see for the trees.
