Non-Zero Day
A while back, I found a post talking about the concept of the Non-Zero Day.
The idea is, to fight depression or demotivation or analysis paralysis, or whatever mental block is between you and what you want to do, you do ONE thing. Doesn't matter if it's just tidying a room, taking the trash out, something. If you're trying to focus, make it one task -- any task -- regarding your goal that you can do. Find something you can start and finish in 10 minutes.
Even if that's all you do, you still took a step toward something. It's still progress.
I am trying to apply this concept to my hobbies. We'll see what happens.
