I also find that starting the writing process on an idea unlocks previously hidden thoughts on the subject matter.
When ideas start flowing, other ideas follow. When was the last time you had a good brainstorm? I haven’t used that word in probably 10 years. Well, good thing I started writing on this topic I guess. Pursue your goals, but before you can do that, you have to remember your ideas, when they come, bet on a record, not your memory.
