I was thinking about power.
What makes a man powerful ? what is the real form of power ?
And guess what I have find !
I was confusing between freedom and power.
Being free doesn't necessarily mean that you are powerful and vice versa.
Also, we are never free as we think because there many elements that limits our freedom.
From those, I can mention social norms.
If you are power, it means you can impose to others what you want to do.
But because you decision about what you impose on others depends on some elements you are not free.
