Some people say they are not creative. Some people say they can't orgasm. I say, these people have not had enough practice. Maybe you will never be Michelangelo, maybe you will not be in a porn movie, but I think you've got a little bit of juice in you, you just need to get it flowing.
So, since I don't give advice for being reproductive, to help you with those creative juices:
Don't worry about your results. Think 'happy accident.'
Use cheap materials. Don't be precious about waste.
Don't overthink it.
You're brainstorming. Doing, impulses. If you find something you like, then you can refine it. But you don't need to be a photo realist to be creative. You know all that abstract art people 'don't get' because a 'kindergartener could do that'? Tal R. Why don't you do some of that? (yes, there's more to it than that, but start there)
Get your hands dirty. Make cookies. Cookies with M & Ms, and analogous colours.
Use colours that make you happy. Why do these colours make you happy? What about sad colours?
You're not going to be famous, you're going to be satisfied. You accomplished something and now you can see it.
I printed some photographs today in the darkroom, and that feeling of accomplishment is magical.
