I'm still unfamiliar with DSM, so I won't make opinions about it...
But I've stumbled upon MBTI, please take note that this is not well accepted in the science community. People has an innate demand to be categorized, but not segregated. #MBTI fanbase has grown lately and is effective in categorizing people without the "mental disorder" label of different personality types.
If mental disorder is a spectrum, or a grid, then we are all crazy after all, many are just capable of managing it well.
