‘我只属于我自己’和‘我是自己的主人’用英语怎么说？

我觉得如果说i belong to myself还不如说i belong to no one (我不属于任何人）来得更有力。但是如果直翻的话应该是 i belong to myself. 我是我自己的主人用i am my own boss 更好些。

1.I only belong to myself.
2.I am my own owner.

I belong only to myself

I am my own master

1.I only belong to myself.
2.I am my own owner.

I only belong only to myself
i am master of myself

I only belong to myself.
I am my own master.
