1. As @harry_ramsay pointed out, you can't self describe as a polymath. You are named a polymath by others after demonstrating mastery over multiple skills usually after death.
Is polymath-ism is a curse?
2. I've felt it's a curse because polymaths can never truly be at home. They have no identity. Nobody will truly understand their multitudes.
@davidavalerio pointed out that having no identity is an identity.
Are polymaths only truly understood by other polymaths?
