Prepare and Perform
Even when you are not ready to do something new, go out and get it done. Do your best and leave the rest.
You cannot prepare for every contingency. Some days you have to run with what you know.
Better to finish something now, than to plan to finish it later.
Done badly is often better than not done at all.
A perfect plan doesn’t exist.
No battle plan survives contact with the enemy.
Prepare when you can, but don’t let lack of preparedness stop you.
Done is always better.
