What to do when you run out of ideas
By all means, don't wait for the right answer to just present itself to you. That's how you ran out of ideas in the first place.
The best thing you can do is explore all of your bad ideas. Do something that fails. Start down the wrong path. And start right now.
As you start moving, little by little, step by step you will start to improve. Even if it seems like you are moving in the wrong direction, that is still better than not moving at all. Before you know it, you will find yourself back on track and headed in the right direction.
Good is the enemy of great. Stop worrying if something is good. It might not be perfect, but that is still better than nothing.
