But, basically, I just crunch PiBs of data, build platforms that inexpensively scale to 100s of billions of writes a day, and generate astrological reports that get sold for much, much more than I make.

My first mentor once told me two lasting pieces of advice to making money:

1) Do not try to know everything. Instead aim to know 5-10% more than everyone else in the room.

2) Learn to negotiate. Essentially, understand what the other party needs and how much they need it. Then, ask for the maximum that they're willing to pay plus the amount that it would cost to replace you.

That advice has been on target for over 15 years. Believe me - are way more rooms out there than you'd think.
