A person appears who is a lot younger than yourself but is really impressive;
in any field of work
and no matter what age you become, I think this is something that always happens.

You are lucky if someone like this shows up
while your body and mind is still flexible.
So just sit back and watch.
They probably are doing something that is excitingly new.
You might even realize what you have forgotten to do.

But the opposite of this is when your mind and body is not flexible anymore
and from giving up or through guilt from what you did not do
it becomes a form of jaundice
ignoring them or not being able to acknowledge them;
in extreme cases finding fault being high and mighty and interfering.

Mistaking youth and noobness is something only acceptable by the youth.
We should not brush off their youth with noobness.
This is not something vital for them,
but I think it probably is for us.
