I made my first $1M last year. There are many good sales and general business books out there. I’ve not yet found a good book on the fundamentals of the software business from someone WHO HAS ACTUALLY BEEN SUCCESSFUL. However, I have found plenty of books and articles by “thought leaders” (full of s*) and failures (full of cope). It seems to me this industry has changed quite a bit over the past 50 years, yet the principles of general business not as much. Perhaps you could start with good business and sales books by people with the tax-returns to prove they know what they’re talking about.
