When your brain starts to feel bad, the best solution, get busy.  When I say busy, I don’t mean ‘busy’ I mean actually busy.  There is nothing on earth as good for the creative’s existentialist breakdown as a full plate.  When you don’t have the time to ask yourself if you are happy, that’s the time that you stop evaluating and start actually being happy.  Feeling productive and important creates a bigger jolt to the creative mind than an afternoon in the park or a day at the cinema.  The trick is, to be busy, but not to be a mess.  No one can be expected to think when they are a mess.  Just like no one can be expected to think when the thoughts aren’t due any time soon.  Your brain needs to be swaddled like a little baby.  Don’t let lazy people tell you otherwise.
