Why Plan to Fail?
"Plans are nothing; planning is everything." -Dwight D. Eisenhower
The actual plan itself is pennies compared to the thinking that goes behind the plan. When the plan is finished that doesn't mean it is complete in the sense of the process of events. For example, I can plan a book signing event to market for my book "You May Already Have What It Takes The Art of Winning" but if the weather doesn't allow me to have the event I don't get discouraged because the plan didn't work. Because the real goal was to market my book. There are a million ways to market my book. The morale of the story is don't be to concern about the plan itself. Be more concern about the plann(ing).
Don't write anything in stone.
Always actively plan out your life with the open mind to adapt to changing situations. Don't bank all your money on a single plan. Remember the thinking behind the plan is more important than the plan. The process of actively planning for changing circumstances is better than passively betting on a certain outcome.
The architectural planning of the leaning towers was flawed from the start. So the final plan is only a product of poor planning. The result of a person not actually taking control of planning their life will be at the mercy of circumstances. Constantly focus your strategies so that your plans can constantly adapt accordingly.
One key to being successful is to weigh all of your options. The better the mind of the planner that is planning the plan the better chance of its success. A mind that doesn't read see but few options because it only sees one perception but a mind that reads see more options because it is able to see the big picture. To be able to see options that others don't see read autobiographies, history, and social science to better sharpen your vision.
