Every relationship, whether romantic, social, or professional, has a power dynamic. Being a confident, valuable man carries across all of your relationships. When you are powerful in that way, you can do whatever you want, and others will love it, simply tolerate it, or leave. The ones that leave are just replaced by others, because people are drawn to valuable, powerful men.
Become powerful, and you'll never have to worry about another person again. They'll all worry about you instead.
