Letting your child learn
As a father I regularly have to remind myself to let my daughter be more like I was. To let her take the tumbles and scrapes and learn in the only way she's going to, that running into solid objects is never likely to be the easy option. Fighting the urge that most in my position feel to make things as easy and smooth as possible for our kids. The current me would wait on her hand and foot clearing all obstacles in her path. The earlier iteration of me would let her get on with it and see what happens.
In this regard the 47 Year old certainly has more to learn from the 22 year old than vice versa.
Many years ago I worked with Neil, writer of this on LinkedIn. Lovely words.
