Dealing with change isn't easy. However, some people seem to enjoy the challenges of change, believing they can handle anything that comes their way. When they face obstacles, they find solutions. And although they may experience moments of uncertainty or indecisiveness, they quickly get back on track, hang in there and eventually make good things happen. Because these people are constantly learning and growing with their changing work environment, they can be labeled as both optimistic and assertive.
Optimism tends to reflect a person's outlook on life and their personality.
Here's a crash course. Typically, it's used to describe behavior that's pushy, abrasive or too forceful. The real difference between being assertive and being aggressive is how our words and behavior affect the rights and well-being of other people. Assertive communication champions our own rights and well-being without violating those of others. It takes their feelings and needs into consideration and shows them respect.
