Need to make a change? Break the pattern. Alter the routine.
A subtle change in tone or attitude can have a large impact. Rather than working to change a person, maybe you look at changing their environment instead. Many people don't respond well to being told what to do, but they can react to new conditions that affect their behavior.
Creating change can be tricky if you aren't aware of the secondary or tertiary effects of your actions. Bringing a new vision into reality is tough and takes foresight and determination.
Headstrong people can single-handedly change an organization through influence or force of will. What if you don't agree with the way they are doing business? You can adapt or remove yourself from the situation.
In times like this, it is imperative that you know yourself. It will keep you grounded.
