Where are you getting stuck? I have different recommendations for general entrepreneurship, marketing/sales, business operations, team/people management etc.

A few books that immediately come to mind:

Navalmanack - @naval
ReWork - Jason Fried and DHH
The Advantage - Patrick Lencioni 

 Thank you!! 

Making money: pricing properly + negotiating. 
Creating systems so I’m not flitting from one task to another without finishing. 
Health management: not working to burnout. 

 For systems, check out Traction by Gino Wickman. Really helped me.
