One thing I will say about my father is that he was very much out in the forefront talking about his beliefs about being a complete fighter and attaching a philosophy to that and teaching it.

We preserve the legacy of my father through an education approach. We award scholarships. We do classes at schools about my father's philosophy and life.

When you ask most American parents why they want to have kids, it's to bring more joy into their lives. So, when you don't feel that all-encompassing joy, it must be that something is wrong with you. I think it's dissatisfaction that the expectation was different than the reality.
