Learning! Keep working and you'll come up with better ideas

There are hosts of tips to trick your brain into breaking through a creative block, from looking at the problem from a different angle to pretending you are a more successful person and imagining what they would do to going for a run or taking a nap.

But what about: just keep trying?

Sometimes you just have to power though.  Keep thinking of solutions.  Try the idea that seems too stupid.  Whatever.  Don't stop!  Ask yourself "is there anything else?"

New research shows that the longer people work on a problem the more creative their solutions become.
