Optimism is a strategy for making a better future. Because unless you believe that the future can be better, you are unlikely to step up and take responsibility for making it so.

Chemistry is not just about what you can make, but how you can make it.

译文：高兴时说的话大多会丧失信用，愤怒时说的话大多会失大体。赏析：人在得意时容易忘形，说话无所不谈，此时说的话往往失真。人在极度愤怒时，思维混乱，言行大多不理智。所以，我们要防止在高兴时言多有失，防止愤怒时言多失态。

我是一个激进分子。
