Believe in something. Even if it means sacrificing everything.
...except when it involves investor's money.
Some takeaways after reading Bad Blood:
1. Listen to people.
2. If you're 19 with a great idea and investors willing to support it, ask for help.
3. Cumulative moral lapses will become a slippery slope.
4. If you're building something to sell to the medical industry, for goodness sake get some medical professionals in there.
5. Don't learn your leadership techniques from a Steve Jobs biography.
6. Don't sleep with someone and make them president of the company (or vice-versa).
7. Strive for diverse opinions instead of some yes men (and groupthink).
8. Fabricating results that can impact human lives will bring on the free press, the FDA, the SEC, and the FBI like a sack of bricks.
