How to live your purpose class/worksheets

I’m going through the how to live your purpose class and I’ve been filling out the worksheets. I’m having trouble brainstorming ideas everyday. I chose something that I’m working towards, but in order to achieve it I need to take steps. I’m really focused on the first step, which is raising money and I’ve brainstormed ideas about this but I can’t really think of anything else I can do around that. Should I brainstorm for stages that I’m not at yet? For example, should I brainstorm the end of the process even though I’m in the very very beginning?
