A time out is when we take time to refill and replenish our creative stash. These moments of quiet reflection are crucial for artists. I have mentioned this necessity in the past and am bringing it up again because it is important. With information and images going out into the world rapidly (lickety-split), there has to be some time set aside to refill an almost empty cup.
Suggestion: Every now and then give yourself a break. Meditate. Take a mini vacation. And, remember to get in touch with real life.
