人目を気にしていたら何もできませんよ。って英語でなんて言うの？

Both of these answers are good ways of saying that you cannot do anything if you care care what other people think. It is so important to do what makes you happy and when others 'expect' something of you it means that those people may want you to be a certain way. This may not be who you really are or may just not make you happy and so being yourself and making our own choices is so important.

You can say care about or worry about, either one of them are fine in this sentence. I hope that this helps :)

Worrying about how others see you may be a debilitating characteristic for some people. They may be overly shy or obsessed with the possibility of failing to create a positive impression.

When you want to explain to someone that they would not do anything if they always care about what others think; then you can say it in the following ways: -You wouldn't do anything if you cared too much what others think -You'd end up doing nothing if you took people's opinions too seriously

Sometimes we worry too much about others and what they think about us, if you want to do something it should not matter what others think if it makes you happy just do it you can simply say 'it shouldn't matter what other people think'

If someone is hesitant about doing something due to the opinions of others and you want to tell them not to worry, you could say any of the following: "You can't do anything if you care what others think", "Don't worry about what other's think, you should always do what will make you happy" or "If you are too self conscious about other's opinions you'll never do anything".

These are all very common phrases, and easily understood. "Enjoy yourself" and "have fun" have the same meaning.
