Learn to work harder on yourself than you do on your job. I’ve worked hard on my personal development, and I must admit that this has been the most challenging assignment of all. This business of personal development lasts a lifetime. But here’s the great axiom of life: To have more than you’ve got, become more than you are. Unless you change how you are, you’ll always have what you’ve got. – Jim Rohn, from his classic “Lessons on Life” gift book.
