I've faced a lot of changes in my life. Some small and inconsequential, some large and very significant. I'm still here and I'm still sane (well, I think I am). The more changes I encountered, the easier it seemed to be to face the next one. I learned to use the five year rule to decide if something was important - would this make a difference in my life five years from now, if not, let it go and adapt. If it would, then try to deal with it in a positive manner.
The older I get the easier and the harder it is to deal with change. I seem to deal with the big things much better than the little. Strange...
How well do you deal with change? Have you noticed any differences as you've matured?
