Have you figured out the second head fake?

I don’t really get what this means (how often do I start my blogs like this) but from what I have researched, it seems that it is about achieving your dreams and living your life with good values. By doing this, the rest will follow. Karma will play its role if you play yours by being a good person. This is a speech given by life coach Randy Pausch. 

I guess that if you have figured out the first head fake you wouldn’t have to worry about the second head fake? Randy then says in the speech that the speech was not for his students but for his three children. Now I’m really confused…I’m not too good with understanding quotes (I think), I want to know exactly what it is you are actually saying. Anyway, Randy obviously had valuable lessons to teach and that’s beautiful.
