Freedom: What is it?

Hello guys, I'm Chris,
today i'd like to talk about Freedom. We consider freedom a gift that our ancestors fought to give us, but what is freedom? You can ask it to four people and get four different answers ... the truth is we don't know. What i'm writing down below is not a definition of freedom (as i've sayed, that's not easy to find) but just my personal idea of what it is. If you have a different idea, please post it as a comment, i'd be very happy to read it. Freedom for me is a state of mind, a person is free only when it has an open mind, a mentality with no limits, free from any stereotype, prejudice, or dogma. After telling this someone asked me: "What if i'm angry with you, can i snap you?"  Of course not, but that makes me think that maybe i should explain myself in a different way: A free person is someone who has a MENTALITY with no limits, there's a difference between mind and the "physic world", you're free to be angry with me, what you're not free about is to express it in the "physic world" by snapping me because that would somehow damage a person. So in other words: you are free to think whatever you want and have your personal ideas, you can also take them to the "physic world" by acting the way your ideas tell you to do but AS LONG AS IT DOESN'T HURT anyone (yourself included, that's why i don't consider a free person someone who kills himself). We always think we're free, but are we really free? I mean when you go buy the last version of Ipod or computer you may think you're free because you're actually buying something with your money, but if you pay attention you've probably heard its spot on tv thousand times saying "buy me" before actually thinking of doing it !
If you buy something because someone or (in this case) something told you, you're just doing what someone else want and not what you do want ! But from the other side you could really need a new mobile phone, maybe your last one has just broken ! So i think this way:
Whenever something makes you want to do an action, you should stop and think "is it really what I wanna do?" If the answer is yes, go on ! If the answer is no, you've just seen how human mind can be conditioned ! You were close to do something you didn't want just because someone else asked you !
Thinking about the world you might have noticed that even if we're free, we do have some rules to follow !
Some of them are physics, you may want to fly but gravity won't never let you do it by moving your arms !
Some of them instead are written by men, and that don't make them less important, if a nation forbides you to kill a human being maybe is just a way of protecting its citizens (yourself included !). The real mistake is thinking that there's no freedom because we have rules. Heraclitus says that nothing can exist without its opposite, it may sound weird but think about it:
As a free man i can say: "Tomorrow i'm going to Spain" but if a pilot from Iberia didn't make a contract that "forces" him to work tomorrow, i may not go to Spain, but from the other side the pilot decided to make a contract with Iberia, he could make a contract with Tap, British airways, Tam or even don't make any contract ! But from the other hand this freedom is also linked to a limitation; he wants to work because he probably need to get some money to live !
He's forced to be free to choose to force him, in other words freedom and limitation needs each other !! You can't have one of them without the other.
I hope i didn't confuse you, Chris
