It’s very easy to sit back and do nothing. Too easy sometimes. It can be hard to do anything at all. Those days where I stare at a messy room or an empty page, and I can’t will myself to do anything about it. Honestly, it can be very easy, at this point, to just cut your losses and give up.
But don’t do that.
Keep trying. You don’t have to continue stuck, staring at what you need to do. You are stuck there, try something else. I personally find going for a walk helps, but anything that takes you away from the situation.
Come back at it with a fresh mind, and hopefully you can go at again. This time you may do it. If not, try again later. The important thing is not to give up. That’s never the answer.
