Public speaking and meeting new people I totally relate to, only in adulthood one seems to become self-conscience, whilst at school you shrugged it off.
Getting out of the comfort zone I agree, however doubt whether I will, so side-stepping this one to enjoying it as much as I can. Now grateful during lock-down having found my balance between the garden and my computer, weekly walks further afield still not quite what you saying, yes get out of that comfort zone and live!
