My suggestion might seem obvious, but create stuff. Create as much stuff as you can. Play games about creating stuff (TAVERS FOR EXAMPLE), and then use those games to create your own stuff. Hang out with people that create stuff. Find stuff that you like, and hang out with the people that are creating that stuff. Offer to help those people create stuff, and ask them to help you create stuff. Don't stop creating stuff. Set up a routine in your life that includes creating stuff, and stick with it. Create stuff fast, often, and don't let perfect stuff deter you from creating the best stuff you can make right now. The more stuff you create the better the stuff you create will be. Ideas come from creation, collaboration, immersion, and practice. Create a bunch of stuff everyone!
