It's hard. Eventually you make a mistake in your beliefs, and (especially if you are in politics, but some other domains too) correcting that mistake means acknowledging that a previous version of yourself contributed negative value to the world.
这很难。最终，你会在自己的信仰上犯错误，并且（特别是如果你在政治领域，但也在其他领域）纠正这个错误意味着承认以前版本的自己为世界带来了负面价值。
