Who we are now is not who we were last year, last week, yesterday or even a minute ago. Life never stands still, no matter what we do. Change is the very nature of existence—our thoughts, feelings, beliefs, ideas, even our relationships are as changeable as rain and sunshine, or night and day. But, as much as change is inevitable, it is not always welcome or easy to deal with. It can upset our world and generate many conflicting feelings.
