In 1965, when Hesse found herself in a difficult creative place after a year in Germany, LeWitt wrote his friend a long letter of encouragement:
“Just stop thinking, worrying, looking over your shoulder wondering, doubting, fearing, hurting, hoping for some easy way out, struggling, grasping,…Stop it and just DO!…Don’t worry about cool, make your own uncool. Make your own, your own world. If you fear, make it work for you – draw & paint your fear and anxiety… You must practice being stupid, dumb, unthinking, empty. Then you will be able to DO!…Try to do some BAD work – the worst you can think of and see what happens but mainly relax and let everything go to hell – you are not responsible for the world – you are only responsible for your work – so DO IT. And don’t think that your work has to conform to any preconceived form, idea or flavor. It can be anything you want it to be…I know that you (or anyone) can only work so much and the rest of the time you are left with your thoughts. But when you work or before your work you have to empty your mind and concentrate on what you are doing. After you do something it is done and that’s that. After a while you can see some are better than others but also you can see what direction you are going. I’m sure you know all that. You also must know that you don’t have to justify your work – not even to yourself.”
