Knowing no knowing knows the now.
Do not mourn discarded plans to ride your camel a thousand miles to reach Mecca, once you know you must climb Chomolungma instead.
The plan is not the goal.
The plan was never the goal.
The goal was the goal.
If the goal changes,
No matter how good the plan,
Change the plan.
So rejoice, grab your mule and climb your mountain.
Reaching the goal is your reward.
It matters not whether you wade through camel shit or mule shit to get there.
