The bubble strategy is something that nothing that Lab mentioned in one in anti fragile is book anti fragile. The idea is to allocate part of your efforts or portfolio to safe bets and then a small part of your portfolio to risky bets, which might go to zero but also have a good chance of extreme positive and return. And I think that's something that applies very much not only to investments, but might apply also to career. Sometimes you do want to expose yourself to risk and do it in a way that ensures that you'll keep trying to succeed when things are difficult.
