This excellent exercise which I got from Barbara Sher will help you to make a starting point for your project. It can also serve as a tool for self-coaching when you are stuck.
Make a brainstorming with yourself (for rules of brainstorming, see here).
First of all, define a starting question, f.ex. "How can I start my online business?". Then, assume different characters and give yourself suggestions and ideas which can help you with your question. For some unconventional results, Barbara Sher suggests far-out characters like:
Imagine you are an old mule-driver, and give yourself advice, then take on the role of a queen of a foreign country and see what ideas you come up with. The only rule is: you have to come up with at least one idea for each character. No idea is "stupid", since the most unconventional ideas are often the best soil for brilliant and realistic ideas to grow on.
