Proper planning saves time and resources!
Think it through before making a move.
Whatever you try to save by avoiding proper thinking, you will most likely pay for, with time and material, during implementation.
Implementation is simple and straight foward when all the possible variations have been previously considered, and the best option selected!
Do you really think you can avoid a thorough plan? Try loosing your directions in the middle of nowhere without refering to a gps; you would be lost, at least till you trace your way back or ask questions.
Always make proper inquiry and investigation before setting out on certain missions.
Some mistakes will simply not be if the procedure is thought through before the first move is made.
As soon as certain mistakes are made, it would cost time and resources to make the necessary corrections, so why make such mistakes in the first place?
Planning well does not necessarily mean spending time; sometimes the best plans are drawn in split seconds. Quality thoughts are not necessarily the ones that consume so much time but the ones that put every possible alternative into consideration for maximum productivity.
Think before you say a word.
Think before you make a move.
Figure it out before you begin to spend because you may just keep spending to correct mistakes that proper planning would have eliminated.
A good plan may be a thought that is properly described verbally or a detailed drawing / writing. The point is that any project worth embarking on is worth being evaluated before starting!
