The other piece of advice that has worked for me well, especially on a professional front, has been to take ones time to respond, and to try not to react. Ive noticed that a quick reaction or retort to any situation usually ends up messy. By reacting I found myself swaying between extreme emotions, letting external situations decide my state of mind calm, angry, relaxed.
There is a dignity and maturity that pervades when we take our time to respond to situations a calmer disposition helps us make decisions more objectively.
By taking time to respond to situations, I found that not only did I get more respect from others, but it also helped me become more rooted and centred.
