The Founder's Dilemmas
Uncle Scrooge comics... though I guess they are sort of business books.
I guess filling out forms on Angel List.
Go work at Google in 98 instead of starting DreamHost. Don't have a home birth. Go (even further) all in on Bitcoin, sell it all (not on mtgox) at $1,000, buy it back at $200, put it all into the eth pre-sale. Then sell at $4K and buy BCH at $80.
Founding DreamHost? Or maybe Bitcoin Builder? Or the children's books I'm working on now? Or "creating" the four kids I'm writing them for!
Ones who bootstrap, especially solo founders.
Freezing time.
By car.
There are no silver bullets. The 80/20 rule. Everybody is interesting. Life is what happens to you while you plan for the future. Start from first principals. Actually do the math. Start something. Good enough is good enough. Never trust a fart.
Helping others and making something new.
Financial economics and/or databases.
Set out on my own.
The death of my son.
