Reddit reviews Sick in the Head: Conversations About Life and Comedy

Wow thanks, I really need to hit a bunch of open mics and suffer some bombs to neutralize all of this validation.

I'm still trying to develop a solid writing habit to be honest, it's very difficult for me to maintain a steady productive flow.

I'd recommend reading Poking a Dead Frog by Mike Sacks and Sick in the Head by Judd Apatow, both are collections of interviews and advice with amazing comedians and comedy writers. You can get some fantastic advice there but mostly it's just inspiring and motivating.

For writing specifically, the only book I'd seriously recommend is How to Write Funny by Scott Dikkers, he was a founding editor of The Onion and it's a slim, no nonsense book.
