As an introvert myself (yes, the same kind who is drained and need to recharge badly after social hours), I actually do all 3 things that you write about.

There are many times where I come across as a person who micro-manage just because I prepare the whole deck myself, but hey doing it yourself and understanding the nooks and crannies, the jargons, the technicalities of it all, these are the only ways I am going to get the hang of it, and therefore being able to present with conviction.

Thank you for telling it as it is. I enjoy your sharing!
