I don't read. 😂 But my problem solving technique is to hone in on specifics. 
What do you want to accomplish with your business? When you answer that write the steps you need to do to achieve that.
If finances are your struggle look up useful spreadsheets. Figure out projections and put together PNL and what not or get an accountant. If its marketing, how do you get yourself in front of more eyeballs? Etc.
But if you have really want to read something I'm told read economic books not business books- Human Action or Anatomy of the State.
