When you are authentic, not hiding behind snark or anonymity, but genuinely letting parts of yourself loose to the world you open yourself up to attacks. It stings, no doubt.
But what you get back in return - advice, good humor, budding friendships, endless support, all where you never expected it - trumps the nastiness ten to one.
Don’t share if you don’t want, but don’t do it out of fear. Shine, and see what happens.
