Colloquial Linguistics

Is anyone else sort of in a uncomfortable elocutionary limbo? The lack of confidence in any specific one, kills the ability to be quick witted & humorous. Which makes public speaking (or even meeting new people) always turn out boring or shit.

Ultimately, this situation is advantageous to you as an individual. Your jack-of-all-trades situation with language makes you more adept as a metalinguist - compared to the average monolingual/monocultural person, you have a greater insight into how language works in a broad social context, and also a window on how thought is affected by linguistic structures for various groups.

You've already shown that you're aware of pitfalls and limitations, so anyone who judges you based on their idea of how you should 'measure up' in one particular dialect or communicative mode should shut the fuck up and start listening properly.

Be confident, be yourself (as someone mentioned upthread), and enjoy a lifelong journey of linguistic discovery.
