Being a creative individual and having a mind that is not relaxed you will run into a few problems. The type of problems are endless. So remember to take some time to relax. Personally I know how hard that can be to do. Because we are so used to always working.
Then when we are not working it feels as if we are unproductive. But you should remember that if you are always working you will eventually get burned out. A good example is a car that is very low on gas overtime you will eventually stop working.
Take a day to relax and refocus at least one day a week. You will start to notice a slight difference in many aspects of your life.
