“Ready, Fire, Aim” is the title of a book by Michael Masterson.  Traditionally the term is ready, aim, fire.  Ready was where you prepared, aim is where you directed your product to go, and fire was the execution.  The idea behind ready, fire, aim is that you prepare first, then execute, and then fine tune as you go along.  Analysis paralysis or paralysis by analysis is the state of over-analyzing (or over-thinking) a situation so that a decision or action is never taken, in effect paralyzing the outcome. A new business idea can be looked at with too many detailed options, so that a choice is never made, rather than try something and change if a major problem arises. A person might be so concerned with trying to make the “perfect” business upfront, that they take forever to pull the trigger.
Starting a business is scary.  You want it to do well and be an instant success.  You plan and plan and continually polish it.  But there comes a time when you must take decisive action with no certainty of the outcome.  Then as you see results you can course correct as needed.
“The Ready, Fire, Aim concept is about velocity, about the profound benefits of moving from an idea into action at the fastest possible speed. But Ready, Fire, Aim doesn’t mean reckless abandon. It doesn’t mean bolting into action before you are ready. It’s Ready, Fire, Aim, not Fire at Will.” states Michael Masterson in his book.  So prepare as much as you can.  But, remember that nothing is ever perfect.  In our striving for perfection we sometimes block our ability to go to market with our product.  I have clients who have spent up to 3 years on developing their collections before ever trying to sell it.  That is a long time.  Perfection is never possible and sometimes really good is good enough.
