Well it has been my experience that dominance may come naturally for many; yet, one allways needs to learn from others. The dominate individual that closes his or her ears to the wisdom of others is a fool.
I have had many mentors in this way of life. Some from books, some real life, others proxy, all have inspired me.
Not surprisingly, in my time I have noticed it is often one's own slave that you will learn the most from.
All knowledge is power.
