“The saying goes that optimists tend to be successful and pessimists tend to be right. And the idea is that if you think something is going to be terrible and it is going to fail, then you are going to look for the data points that prove you are right and you will find them. That is what pessimists do. But if you think that something is possible, then you are going to try to find a way to make it work. And even when you make mistakes along the way and even when people doubt you, you are going to keep pushing until you find a way to make it happen”
- Mark Zuckerberg

“Human nature makes it hard to accept the idea that the willingness to live with some losses is an essential ingredient in investment success”
