When plan time is over, you have to put away your toys and get to work.
No more messing around. No more diversions. No more delays. No more hiding.
A plan is only as good as its implementation—but not the opposite. A beautiful plan isn't that great if it can't or doesn't get done.
I enjoy planning—if only because it's the best time to try to avoid the mistakes I made last time—but not nearly as much as I enjoy doing. Possibly I like that inflection point even more where the plan falls away and leaves raw doing in its place. It's not about abandoning the plan, just knowing that it has served its purpose and now it's time to move on. Otherwise you end up serving the plan, not serving the purpose.
