My biggest failure in life is not knowing what people really want out of the internet/web/apps. I'm constantly surprised at how things became such big successes. Instagram? eh, that'll get used by 100 people. Snapchat? That'll be forgotten about in 2 months. Facebook, meh, seems boring. And so on... I'm wrong so damn often because I just can't imagine wanting to do what other people get super excited about. I don't think there's anything wrong with all that they do, my brain doesn't work like that though, I really wish it did! All these successes are obvious in hindsight.
