“If you want to be wealthy and happy, learn this lesson well: Learn to work harder on yourself than you do on your job. What you become is far more important than what you get. The important question to ask on the job is not “What am I getting ?” Instead, you should ask, “What am I becoming?” What you become directly influences what you get. Think of it this way: Most of what you have today, you have attracted by becoming the person you are today.  Income rarely exceeds personal development. To have more than you’ve got, become more than you are. Life is all about creating skills and value and taking those skills and value to the marketplace and seeing what it will return for you.”
