Creativity builds off itself.
“You can’t use up creativity. The more you use, the more you have.”Maya Angelou
What you’re creating doesn’t even have to be good, certainly not in the beginning. That’s not the point. The point is to start creative work to inculcate the habit of thinking differently and having something to show for it.
“The most important possible thing you can do is do a lot of work.”Ira Glass
Since it can be hard to think of new ideas off the bat, the best way to start creating is to simply copy others. Re-draw that Monet piece. Copy the prose of your favorite writer. Try to get into the mind and shoes of an artist you admire. After copying for a while, you’ll soon to develop your own voice.
The more you create, the more you’ll have to play with. You can showcase your best work while refining your old. You can be learning new techniques to integrate into your existing skill set. The palette is indefinite.
Once you choose yourself and do the work, people start to look at you like the artist they admire. So keep creating, even on the days you don’t feel it. Keep building the creative muscle.
