I think it's useful to maintain a discipline of mental hygiene and to isolate yourself from the constant flood of news, good and bad. If you get too focused on the success stories you'll be constantly worrying about whether you're missing out on something good, which impedes your ability to actually get anything done exceptionally because you're doubting your own thing and your own place in the world all the time. In the wise words of Charlie Munger: "Someone will always be getting richer faster than you. This is not a tragedy."
