从长计议

zhè jiàn shì yīng gāi cóng cháng jì yì bù yí cāo zhī guò jí

这件事应该从长计议，不宜操之过急。

We must talk this over at leisure. It's no good being over hasty.

cóng cháng jì yì nǐ bù xū yǒu rèn hé lǐ yóu jiù kě yǐ cóng xiàn zài kāi shǐ qù cháng shì tǐ yàn xìng fú

从长计议，你不须有任何理由就可以从现在开始去尝试体验幸福。

In the long term, you can start practicing being happy right now without any obvious reason.
