"A good plan, executed now, is better than a perfect plan next week."

I like this one because you can never make a perfect plan. Although we always have alternative, we need to consider the resource and limitation. One's perfect plan could be the worst for other people or even the whole organization.
What we should be is to find out one good plan, solve, and correct the error. This is better than staying in the original place to discuss the problem.

However, in the other hand, if the plan is for a long term project such as a 5-10 years construction for the organization, comparing the time last, we should have longer time to discuss. Therefore, to plan for the good plan or perfect plan is compared to the importance of the project.
