My personal story about not making hasty decisions: I worked on a GIF animation this week and got angry because it just didn’t work. I was about to stop the whole project when I reminded myself to just take a break and work on it later. A few hours later I looked at it again and felt better about the whole thing. I changed stuff and worked on it and now I’m on a good way to finishing it. If I decided to stop it in my bad mood I would have never worked on it ever again.
So if you are emotional, try to take a break. Calm down and look at your creative problem with a fresh set of eyes. Only after the break do you decide what to do with the projects. If we always made these hasty decisions, we wouldn’t finish anything.
