You may have noticed the odd times when something is irking you, putting you into a bad mood, and you sit down at your easel and do good work. While it’s not as pleasant as when you’re in a good mood and everything is coming up peonies, it works to your benefit in another way. In my experience, a bad mood helps the attention span and the critical faculties–not necessarily to be more creative–but with a wider vision and a sharper focus.
I agree with you! I get tonnes of chores done around the house when I'm
pissed off or upset, whereas when I'm blissfully happy or content, the sink
in my kitchen is dangerous to go near!
