People often say discretion is the better part of valor. I agree. I would also add that restraint often is just as useful. You could argue that restraint and discretion often come hand-in-hand, but I don't think so. A person can be discreet without having restraint. It all depends on the situation. Some require restraint, more personal than others at times, and some require discretion.

It all depends on who you have to deal with and what the situation calls for.
