We all have creative blocks now and then. It happens to everyone.
This short video suggests that the best way to overcome creative blocks is to just keep thinking. Very simple, right? As this video from The Science of Us explains, psychologists found that people tend to give up too early in the brainstorming process, and if they just kept it up a little bit longer they would come up with lots more ideas.
It seems the longer you brainstorm on a subject, the more creative your ideas become. Makes sense.
