Nós não nascemos humanos, nós nos tornamos

We are not born humans, we become... How beautiful is that... How true, some might agree. We study and learn so much, we are so bright and smart, but sometimes it is so hard to describe things. Like right now, I can't express how I understand the saying 'Nós não nascemos humanos, nós nos tornamos'. Our heads have so much information, so advanced and the simplicity is lost in between. Or it is just that hard to interpret. Or do we not need words anymore? Can we speak without talking? May it be the true Human Being, the perfect one?
