Consistency
Being consistent really matters. Consistency is key to simplicity. If we are consistent, it goes along way toward keeping things as simple as possible and reducing the confusion associated with unnecessary complexity.
Consistency is an exercise in prevention. I consider it an investment — a good investment. We all know prevention is better than response after the fact. Preventing a fire is far better than reacting to one. It saves time, energy, and mood of ourselves and those with whom we communicate. It also saves money in the long run. Being consistent is worth the effort. It pays dividends that sometimes go unnoticed.
