Everyone is creative to varying degrees. It may not manifest in drawing or painting, but its something we are all blessed with. It’s us who nuture or let it die however. Creativity comes in waves like nausea. You have to let it out and you will feel better. Ride it because you never know when the next wave will come. When it does your muscles memory will carry you to new heights.
