That's My Lesson For Taking A Vacation:

I Think The High-tech Industry Is Used To Developing New Things Very Quickly. It's The Silicon Valley Way Of Doing Business: You Either Move Very Quickly And You Work Hard To Improve Your Product Technology, Or You Get Destroyed By Some Other Company.

I Think It's Important To Reason From First Principles Rather Than By Analogy. The Normal Way We Conduct Our Lives Is We Reason By Analogy. [with Analogy] We Are Doing This Because It's Like Something Else That Was Done, Or It Is Like What Other People Are Doing. [with First Principles] You Boil Things Down To The Most Fundamental Truths…and Then Reason Up From There.

You Have To Be Pretty Driven To Make It Happen. Otherwise, You Will Just Make Yourself Miserable.
