Reading shapes and finding the idea
After a while – 30 minutes, an hour, or more if I have the time and haven’t found anything yet – I usually start seeing shapes that remind me of something. “Hey, this looks like an alien structure!” is what I think when I see this weird shape on the left. When you start getting the idea, start refining it and working a bit more in the direction of the idea you have. If you see a forest, for example, start adding some trees!
