Is your skin thick enough?
Gotta agree with Barbara and Len, its what we see of ourselves reflected in the writing of others that makes a difference.
On the “thick skinned” topic, I like Brian Johnson’s little mantra “I am totally independent of the good or bad opinion of others” – don’t always achieve it, and it is something to aim at.
Seems to me that skin needs to be thick enough to keep the important stuff inside, and not be too easily damaged, and also thin and flexible enough to get the maximum from the experiences available to it (touch, cuddles, a summer breeze).
30 years ago I was running 4 miles a day on gravel roads, barefoot, so my foot skin was almost half an inch thick. Now I wear socks and boots and it is much thinner.
It seems to me that we need to be open to the contribution of others, and we also need to be very clear that their issues are theirs, not ours. No simple answers.
