Big goals don't have to happen all at once. Allow yourself a set time each day, perhaps 30 minutes. Day 1 might be to brainstorm ideas. Day 2 might be to expand one of your ideas. Day 3 might be to sort out possible contact people ... and so on. The critical part of this is to return to it on a daily basis. Small successes build momentum, and your big goal will keep getting closer until it is within your grasp!
