If you have some concerns about your job, you need to create a concept or make some decision but you’ve been going around in circles just thinking about it without actually finding a way to solve the problem, you had better sleep on it.
For more than 20 years I’ve been doing cartoonist work. I came to understand just one thing. That is, when I can’t draw, when I worry about something, and when I am exhausted, 「to sleep」is the only way (to solve them, ed.). Generally speaking,「when there’s something (bothering, ed.), postpone the decision making and take a sleep for the moment」. Forcing myself to stay awake for long time won’t result i a my progress. I’d rather preserve the strength for later, in order to recover the loss (from the unproductive time, ed.). That’s said, I’ll go to bed now.
A cartoonist, Ken Akamatsu（@KenAkamatsu) is known for his manga “Maho sensei Negima (Magic teacher, Nagima)”. He recommends you go to bed when getting stuck with your work or study. This is a profound advice from an experienced cartoonist.
When there’s nothing I can do 「sleeping」or just 「doing nothing」is recharging, refreshing in a great extent. Moreover, deep, long sleep from the day through the night can bring a good feeling like you’re getting “updated”. Having a good long sleep makes me feel updated. To what extent can be dependent on how exhausted you are, though.
I think that’s how humans are created. Otherwise, we can’t put up with the dairy stress.
Indeed, sleeping and performance have a reciprocal relationship. Hitting the bed might sound simple, but it’s actually vital for better work performance. If you are feeling stuck, just go to bed early and refresh your mind.
