War metaphors invade our everyday business language: we use headhunters to build up a sales force that will enable us to take a captive market and ma… - Peter Thiel

The rest of their generation was left behind, but the wealthy Boomers who shape public opinion today see little reason to question their naïve optimism.

The entrepreneurs who stuck with Silicon Valley learned four big lessons from the dot-com crash that still guide business thinking today: 1. Make incremental advances Grand visions inflated the bubble, so they should not be indulged. Anyone who claims to be able to do something great is suspect, and anyone who wants to change the world should be more humble. Small, incremental steps are the only safe path forward. 2. Stay lean and flexible All companies must be “lean,” which is code for “unplanned.” You should not know what your business will do; planning is arrogant and inflexible. Instead you should try things out, “iterate,” and treat entrepreneurship as agnostic experimentation. 3. Improve on the competition Don’t try to create a new market prematurely. The only way to know you have a real business is to start with an already existing customer, so you should build your company by improving on recognizable products already offered by successful competitors. 4. Focus on product, not sales If your product requires advertising or salespeople to sell it, it’s not good enough: technology is primarily about product development, not distribution. Bubble-era advertising was obviously wasteful, so the only sustainable growth is viral growth. These lessons have become dogma in the startup world; those who would ignore them are presumed to invite the justified doom visited upon technology in the great crash of 2000. And yet the opposite principles are probably more correct: 1. It is better to risk boldness than triviality. 2. A bad plan is better than no plan. 3. Competitive markets destroy profits. 4. Sales matters just as much as product.

We didn’t assemble a mafia by sorting through résumés and simply hiring the most talented people. I had seen the mixed results of that approach firsthand when I worked at a New York law firm. The lawyers I worked with ran a valuable business, and they were impressive individuals one by one. But the relationships between them were oddly thin.
