1Warm up. Don't try to brainstorm with just a cold start. This is like breaking out into a full run without a light jog first! Do a quick exercise that gets your head in that space, such as making a menu for your next week's worth of dinners, or coming up with a wish list of things you'd like to accomplish in work, school, or whatever it is you're doing.
1Do some research. Do some research on what people working on similar projects have been doing. Google is your friend in this adventure. You should not be looking at what others are doing in order to copy them. Instead, you should be seeing where their ideas fall short or what pieces of their project might fit into yours.
