As Simon Sinek very aptly said about a plan..

“Always plan for the fact that no plan ever goes according to PLAN.”

Seth Godin echoes the same sentiment and mentions that a MISSION works better than a plan which is sure to fail since it is so futuristic..

Adopted from the following great quote of Seth Godin that mentions why MISSION is preferred over a PLAN..

“Plans are great but missions are better. Missions survive when plans fail, and plans almost always fail.”
