A good plan is like a road map: it shows the final destination and usually the best way to get there.
The ultimate security is your understanding of reality.
You will live your life secure in that you are no longer manipulated by what other people want you to do and be, but are directed by your own inner desires.
Don't be afraid to fail. Don't waste energy trying to cover up failure. Learn from your failures and go on to the next challenge. It's OK to fail. If you're not failing, you're not growing.
You will now have a starting place and a destination, and you will be able to determine what it will cost you to get there. You will be going someplace.
