Tell me that it wasn't all for naught.

告诉我那一切都没有意义。

Now I wondered if it was all for naught.

现在我则怀疑所有这些是否白搭。

Thank goodness my fears were all for naught.

感谢上帝我的所有担心都是多余的。

All your code is for naught if users can't hop online and buy items from their favorite vendor or find out how much the newest abstract watercolor from their local gallery costs.

如果用户无法上线、无法从他们喜爱的厂商那里购买商品、无法在当地美术馆中找到最新抽象水彩画的价格，那么您的所有代码都等于零。

Either you see yourself as better than someone and you get lazy and perhaps arrogant, or you see someone else as better than you and you feel like all your hard work is for naught.

也许你会觉得自己比别人出色而变得骄傲自大，并开始懒惰傲慢起来，也许你觉得付出同样的努力甚至比别人更多，但所得恰恰相反，因而开始质疑自己的汗水付诸东流。
