When I'm having trouble creating, I use this technique and it works every time.

Just start. Sometimes you’ll have to force yourself to do it—make anything without worry, just to get moving forward. The longer you go, the more momentum you build.

Every now and then, you’ll discover something that feeds the fire. Keep exploring, keep making. Eventually, it’ll feel like it’s flowing on its own. From there, all you have to do is maintain it.
