These are 10 rules that came hard way. Not from professors in stuffy college classrooms who make their money teaching but in the trenches. Writing real software that makes real money.

These are the 10 most important lessons I learned in my 25 year career and they've helped me make over $4 million.

  • The importance of using custom scripts
  • Question everyone
  • Understand your tools
  • The truth behind floating point numbers

By the end of the book, developers of all levels of experience will have the confidence to apply these rules to your software development journey.
