This also translates into:
- “Why am I so motivated when it’s really late?”
- “The best time to make ideas is through sleep deprivation!”
- “I want to do so much more right before bed and I don’t understand why!”
So basically when you stay up way too late it effects your problem solving ability and your ability to make decisions. 
Do you want to know a possible reason as to why that “I stayed up really late and now I feel so creative and willing to draw!” feeling happens? Because your self-critique center is shutting down because you’ve been awake for too long.
You are always as creative and able to do things as you were when you were awake. That potential doesn’t just disappear.
Difference is— when you’re wide awake you have a stronger problem-solving and decision-making center, which is obviously related to self-critique. Being tired doesn’t necessarily make you more creative and motivated, being tired forces you to quiet that part of yourself that holds you back.
Something to think about.
Hah, well, that explains a lot.
Any advice on turning the self-critique off, other than sleep deprivation? Because “Shut up no lalalala LOOK NO IT’S FINE LOOK JUST LET ME WRITE I CAN EDIT IT LATER” doesn’t seem to be working.
