I come from a close, loving family. I have three elder brothers.

My parents owned a wood supply business.  71 When I was a kid, people used to laugh at my dad and say his volunteer work was his business and his business was his hobby .That rubbed off on me. For example, I was a Big Brother in high school, and I continued doing volunteer work in college.

In 1979, just before graduation, my brother Mark asked if I’d like to help him start a software company.  72 And I was happy that later it became very unusual in the software industry. Once I started working, I continued to volunteer.

  73 So I volunteer to company the elderly persons who live alone. I met Malcolm, who’s physically healthy.  74 He is also interested in my work. He often says “You can get caught up being the CEO of a half-billion-dollar software company very quickly.”

I learn kindness, humility（谦恭）, a positive outlook on life from Malcolm.  75 But we have been together for five years and there is no end in sight.
