what does self imposed mean? please explain in a simple way thanks

Self-imposed means something that you have decided for yourself. For instance, if you've decided you need more sleep, your 9:00 bedtime is self-imposed.

Sure! "Self-imposed" is an adjective that describes something that is voluntarily or willingly placed upon oneself. It refers to a rule, restriction, or responsibility that a person chooses to enforce upon themselves, instead of it being imposed by someone else or an external authority. It means you have made a decision to set certain limitations or expectations for yourself without anybody else telling you to do so. For example, if you decide to give up sweets as a personal challenge, it would be a self-imposed restriction because you chose it for yourself.
