"自分の目的のために他人に使わせるなら彼らは自分たちの目的のためにあなたを使うでしょう"

Simplified Meaning:

When you let people take advantage of you to achieve something you want, they will continue to take advantage of you to get what they want. Imagine if you help a friend with their homework because you want them to like you. At first, it might seem okay because you're getting their attention. But soon, that friend might keep asking for help, not caring if it's too much for you, because they want to get good grades without doing the work themselves. In history, there have been leaders who promised support to groups of people, asking for their help in return. Once in power, these leaders sometimes forgot their promises and used their supporters to stay in power, not really caring about the original agreement. In everyday life, it's important to set boundaries and not let others take advantage of your kindness. If someone at work always asks you to finish their tasks, you might initially help to be a good colleague. Over time, they might expect you to do their work regularly, making you feel overburdened and stressed. By being clear about your limits, you protect your own interests and ensure that others respect your time and effort.
