Recently, I witnessed a sales representative handle a customer's temper tantrum with admirable aplomb. I watched a parent calmly handle a child who had done something he wasn't supposed to. I heard a story from an employee who was maintaining restraint to allow a situation to correct itself. She could have released her arsenal of resources and buried the person causing the problem, but she practiced restraint.
Restraint is an important skill to cultivate.
When you master it, you have more control over situations and yourself so that you can function effectively. Restraint prevents you from saying what's really on your mind before you cool down. A lack of restraint can be irresponsible. Sure, there are brilliant business moves that transcend our past limitations, and some rules, barriers and customs definitely need to be broken. On occasion, we even plan not to plan to allow for spontaneity and serendipity.
