just... be creative when you have something creative to express and the expression brings you joy, happiness, satisfaction, or any other reward of your choice. be spontaneous for similar reasons. don't do it because someone has attached an artificial "you are now leading your best life" reward to the mere fact of creativity or spontaneity - that's just reactive.

truly authentic creativity and spontaneity would leave room for conformity if that's what made you happiest in the moment, because why should the fact that everyone else also does something prevent it from being a worthwhile thing for you personally to do?
