Focus on learning how to build wealth and nothing else. Do what one of the richest men is said to do, read 100 books about building wealth and dedicate 1000 hours toward becoming financially savvy. That 1000 hour investment will change the course of your life and the lives of your children.
Read every book you can about millionaires, anything you can get your hands on. One of the least expensive ways to do this is by taking advantage of the public library. It's cheap and it will give you access to an unlimited supply of material. In the beginning stages you should start by reading material that will help you to start seeing the world through the eyes of an investor/entrepreneur instead of always seeing the world through the eyes of an employee. Making that mental transition is extremely important.
"Rich Dad, Poor Dad" by Robert Kiyosaki is an excellent book to begin with. Another good book to begin with is "Build Wealth" by Russ Whitney. These books will expand your mind and point you in the right direction. Also be sure to read a few books about building and repairing credit. "How to Make Your Credit Sparkle" by Ameen Kamadia will teach you how to build credit, but for credit repair there is no book better than "The Credit Secrets Bible" by Terry Price, Consumer Education Group.
You will learn something valuable from every single book you read. After you have read these books then you can move on to the more specific 'how-to' books that get you revved up but don't give you a plan of action. You only need to read those books once in the beginning. Education is the key to get started immediately.
