You have to think of your brain like a sponge and you take it into your hands and squeeze it. You wait to see what comes out and then you watch it bounce back. You push it to its limit and watch it make its way back.
That is a never ending resource. Break that creativity against the rocks, watch the ocean of the world take it away and bring it back.
The world is your ocean and your creativity contains all of it. So what are you watiing for. Squeeze.
