I don’t want to write too many words on this, because I am about to ask you to read this blog post by Frank Chimero. Read it entirely, read it thoroughly. He composed a list of all the things he learned about productivity, and actually, about general happiness as a workaholic. It can pick you up. For example, he suggests:
Dump your brain on to a sheet of paper—every single thing you could hope to do in the next 3 to 4 months. Then, look at your task list. Have the author sign each one. Did you write it, or was it fear, that nasty tyrant in your head? Cross off anything written out of fear. Listen: some drudgery is unavoidable, but you’re living your one and only life. You get to drive; no bullies at the wheel.
… And after a while, Frank comes back to that sheet of paper:
(…) Many of the things you thought you needed to do in the next few months were left undone without noticeable consequences. Perhaps now you can now cut their weight. “Goodbye, heavy friends. Maybe someone else will give you the attention you need.”
