Lol - am not 21 but get mistaken for 21 - why? It is not a lack of maturity, heaven knows - but that is the way I am sometimes perceived - is it a compliment - of course, it is (a backhanded one) - for example why do I give off the impression that I don't read substantial texts? It baffles me that given my education level and the way I write as a nonnative speaker, isn't it foolishness and a complete lack of discernment to assume I am an airhead? 🤷♀️ You just cannot be a good writer without being a voracious reader (and I don't mean Medium). Period.
Sorry for the rant - just thought of it when I read the part about wisdom
