Your plans must be kept secret!
"Your plans must be kept secret! Do not divulge too much, people will obstruct your plan. Sometimes, silence is needed to achieve your target.
Skillfulness in action is the ability to accomplish great tasks with minimal resources. Compute thoroughly!
Do not be paralyzed because of risk or because of fear. Can you do something about the risk? Take action!"
from Achieve the Impossible : The Golden Lotus Sutras on Spiritual Management by Grand Master Choa Kok Sui.
