Discipline Breeds Success
If a person has many faults in different areas and is confused about where to start, he should select one trait and work specifically on it. It takes self-discipline to correct a trait. To overcome a fault, your intellect must rule over your desires.
Once you've gone through the process once, this will help you correct many other traits.
Realize as well that all character traits are dependent on each other. If you correct one trait, this will automatically be a stepping stone to correcting other traits.
