Freedom is often to be defined as the right of a person to do what she/he wants without any hindrance. But freedom also have limits.

First of all, you cannot hurt other people through verbal, physical or even emotional way. That will fall to bullying.

Next, you cannot actually do 'all' things you want to. 

Finally, freedom is limited because it is needed to maintain peace on the earth. 'Cause imagine a world with no limits. It'll be crowds of fights, robbers seizing others' thing with no second thought and worst everyone killing each other.
Hope this helps you. :)
