Having too many active goals will make you crazy. You’ll always be running around from one idea to the next.
Pick a limited number of important goals you want to focus on for the next few years. Stick to those. Keep reducing your number of goals until you feel free and focused.
Your goals should make you happy. If you hold a goal in your mind and it doesn’t make you happy, get rid of it immediately.
Don’t be afraid to spend your whole life working on a goal. I suspect people who do that are happiest in life, because they feel they’re doing something worthwhile and timeless. I don’t have a “lifetime” goal yet. I plan to change that.
Keep a list of “inactive” goals. That way if you get a brilliant idea, you have a place to write it down for future reference. When you complete one of your existing goals, this list will come in handy.
