A few ways I've learned to Personally Develop myself;
Reading is fundamental and a few books I would recommend;
"Think & Grown Rich" by Napoleon Hill
"Developing the Leader Within You" by John Maxwell
"The Measure of Our Success" by Marian Wright Edelman
(Of course all of Dean's books!!!)
I do read the Bible also everyday
Some speakers I love to listen to and everyday I do for at least 10 minutes everyday;
Les Brown - Motivational Speaker
Bishop T.D. Jakes - Founder of the Potter's House
Zig Ziglar - Motivational Speaker
Art Williams - Motivational Speaker/Self-Made Billionare

You have to work on yourself before you can help others.
