量力而行

You can use it as a verb phrase. It often follows a suggestion or a plan. You might say, "We should 量力而行." It works well when discussing budgets or workloads. It is a gentle way to say "don't overdo it." You can use it for yourself or others. It sounds wise and responsible.

Use it when a friend wants to run a marathon without training. Use it in business when a project seems too big. It is perfect for charity or helping others. You want to help, but you must stay healthy. It is great for spicy food challenges too! If the chili looks scary, 量力而行 is your best friend.

Do not use it to discourage someone's dreams. It can sound a bit like "you aren't good enough." Avoid it if someone is already mid-crisis. They need help, not a lecture on limits. Do not use it for very tiny, easy tasks. Saying it about brushing your teeth sounds sarcastic. It is for significant efforts or risks.

This phrase comes from the ancient text Zuo Zhuan. Chinese culture values balance and harmony. Overreaching is seen as a path to failure. It is better to succeed at a small task than fail at a huge one. It reflects a Confucian focus on self-awareness. It is about being honest with yourself.

A common partner phrase is 尽力而为. That means "do your best." While 量力而行 focuses on the limit, 尽力而为 focuses on the effort. You often hear them together. Another variation is 力所能及. This describes things already within your power. Use 量力而行 when you are still deciding.
