How do you get to know a character in a novel? Does the author just list off their personality traits, or try to describe their humanity in a couple of sentences? No. This is considered bad writing as far as I’m aware — “show, don’t tell” the old truism goes. Instead you learn a person bit by bit (just as in life) through their gestures, mannerisms, statements, beliefs, actions, and so forth.
So why is it that when people describe themselves on websites, they think that summing up their identity in two sentences is the way to go about it, that they’re even capable of this? “Show don’t tell” may be a truism, but I think it holds here. I learn much more about a person by seeing them discuss the things that capture them and show the things they make or do.
