If you could instantly become an expert in any field, what would it be?

Human Psychology

Public speaking. I can make a shit ton of money!

Happiness!

Well to start with there are several fields that I would wanna be expert in. But if told in a sequence, I would first like to master the art of well knitted communication and story telling. I believe this is a core skill and irrespective of any role you are currently, it would come handy and win your rapo amid the competition. Other than this I would like to become an expert in knowing the art of validating an idea of a startup just like how experienced investors do within 5-10 minutes. I know it might be difficult and some of the sharpest minds have mastered it in quite an early age of their career. I am still exploring out ways to master this second skill.
