What I do regret is working too hard sometimes instead of really enjoying my youth. I'm trying to make an effort to stop and smell the roses now.

People have always had difficulty saying my name or were resistant to calling me 'Sir' even though my name starts with 'Ser.' Growing up, my family always called me Darius.
