Hey David! How are you doing!? :) Thanks for the question.
I type really fast :P also, I type things and use things that make it so I don't have to type as much in the future. My GitHub AMA, oss project generator, semantic-release, prettier, etc. etc. etc.
Also, I should mention that even though I churn out a lot of stuff, I don't think I really do a whole lot more than other folks. I just make what I do public (if I can). Recording talks and workshops, doing tech chats and livestreams, and open sourcing as much as I'm able to (even work stuff) gives the illusion that I'm doing a ton of stuff.
Good luck!
