Don't you know you can't do anything about people?

You cannot convince people to love you.

It isn't possible to change your behaviour and still be the same person you were before.

You cannot help people permanently by doing for them, what they could and should do for themselves.

you can't get away from yourself by moving from one place to another.

And you cannot build a home for your worth inside of another being.

No one comes back from the dead, no one has entered the world without crying; no one is asked when he wishes to enter life, nor when he wishes to leave.

People are never able to outperform their self-image.

One can never ask anyone to change a feeling.

You can’t help the poor by becoming one of them.

No matter what they wish for, no matter how far they go, people can never be anything but themselves. That's all.

One cannot change, that is to say become a different person, while continuing to acquiesce to the feelings of the person one has ceased to be.

...You can't save someone who doesn't want to be saved.

You can’t make a dog happy by forcibly wagging its tail. And you can’t change people’s minds by utterly refuting their arguments.
