In my experience, creative ideas coming out are in direct correlation to the amount of new, interesting, and even challenging information coming in.
Most people just view/listen to/read the same stuff every day.
Be different. Consume information, ideas and viewpoints that cause unconscious creativity through agitation.
- Read something every day you don’t normally read.
- Consider a viewpoint opposite yours on some crucial issue each day.
- Go to a new place, eat a new food, talk to a new person each day.
The more you “challenge” yourself and get out of your comfort zone, the more quantity of quality new experience you put into your head… the more creativity will spontaneously pour forth.
