Survival Tip #256
Do It Right The First Time
When attempting to complete a task there are always ways to cut corners to get it done faster. Faster is not always better. Many times hurrying a project will create an end result that needs to be redone, which in turn doubles the amount of time you have invested in the task. Save yourself time and energy by doing things right the first time.

Measure twice, cut once. Applies to all sorts of tactical decisions as well.
