Physician, heal thyself

This is going to sound silly. It does to me, anyway.
It sounds silly because I think it overstates the obvious, yet the fact that it's obvious makes it no less a source of wonder to me.
Lately, I see the line between myself and other people growing increasingly blurry.
I notice more and more how identical to others I am, in good ways and bad. It goes beyond mere similarity most of the time.
There's this woman I know who I can't stand because I think she's arrogant. Haughty. Sanctimonious. But lately, as I look at her and silently make this evaluation to myself, I see the same traits in me. And I also see the same self-doubt manifested in my actions that I notice in hers.
I see how people react to stress, and as I mentally take them to task for losing their cool, I'm reminded of my own frequent inability to deal with difficulties in constructive ways.
I criticize someone for craving attention, and remember my own ego and its quest for praise.
I harbor resentment against a friend for pointing out my faults. Then I recall the many times I've done the same to others, and how hurt I felt when they harbored resentment against me.
But this mirror also reflects positive images.
In karate class, I see someone execute a technique effortlessly and with fluidity and say to myself, "I think I can do that, if not now, then eventually."
My best friend told me a long time ago that if we see something we admire in others, it's only because we see that same potential in ourselves.
Lately, I've also seen the other side of that coin, that if I see something in others I don't like, I often need only look just under the surface to see that same weed growing in my own garden.
Yes, I think I'm overstating the obvious. I suppose it's like marveling that water is wet.
But I marvel just the same.
