Some people really seem to enjoy saying that they don’t—perhaps this lets them off the hook to change themselves. But yes, people absolutely change. I see it all the time. You can change, in ascending order of difficulty, your thoughts, beliefs, emotions, behaviors, and personality. Making these changes within yourself will encourage you to make changes in the world around you: in your romantic and familial relationships, work, hobbies, creative endeavors, and maybe even on larger scale social or political issues. Changing yourself may also allow you to better accept aspects of life that do not change, like past mistakes, illness, loss, tragedy, and mortality.
