The very first company I started failed with a great bang. The second one failed a little bit less, but still failed. The third one, you know, proper failed, but it was kind of okay. I recovered quickly. Number four almost didn’t fail. It still didn’t really feel great, but it did okay. Number five was PayPal.
The single most important top-level trend is the shift to mobile.
I’ve been developing mobile for years before anybody else really thought it was that important.
