I love how to books. They are the closest thing you can get to having the author as a mentor. But they aren’t the same as actually having a mentor. The reason they fall short is books can’t look at where you are and answer the question “What’s next?” Books also can’t do three-way calls with you, they can’t do 2 on 1’s with you, books can’t help you build your team.
A mentor can though. A mentor can also give you a kick in the butt when you make stupid mistakes, and you will. The fact is, you will always be the single biggest reason that you experience failure. We all get in our own way from time to time. A mentor can dramatically reduce your mistakes.
So, don’t try to go it alone, if you want to win, get a mentor.
