In any creative industry, the fact that others are moving in a certain direction is always proof positive, at least to me, that a new direction is the only direction.
But I love that feeling of utter depletion: It is an ecstatic sense of having committed myself to the absolute limit. But after recharging at night, I'm ready to go the next morning. Isn't that what life is all about?
Follow your bliss. That which you love you must spend your life doing, as passionately and as perfectly as your heart, mind and instincts allow. The sooner you identify that bliss, which surely resides in the soul of most human beings, the greater your chance of a truly successful life. In the act of creativity, being careful guarantees sameness and mediocrity, which means your work will be invisible. Better to be reckless than careful. Better to be bold than safe. Better to have your work seen and remembered, or you've struck out. There is no middle ground.
