WISDOM

Keep this in your mind.  

Plans are sometimes stupid, partially unworkable, full of holes, etc. 

BUT

planning is always important; intrinsic to positive accomplishments.  

Don't jump into something without planning.  Realize before you start that every phase of your plan might not work or won't work well.  No matter - don't throw the bathwater out with the baby.  The most important part of the plan is the final goal - that shouldn't change. Be flexible about how you get there.  Don't lose your hair because some phase of the plan doesn't work.  Keep chargin' forward!
