Where does creativity come from? Inside a person, I think. Inspiration comes from outside of a person. So if a generally creative person begins to feel a lack of creativity, that person would turn toward their source of inspiration to refill their feeling of creativeness.
So the first step is to figure out where a person’s inspiration comes from, find that source of inspiration. And then spend time thinking, questioning, analyzing and figuring out that inspiration. An ongoing amount of time.
I think even extremely creative people have their tough times, right? Even the master’s had their sketches, unfinished paintings, even bad paintings.
The key is to keep going. Start over, if need be, but at least keep moving.
