Life's all about the choices you make. Sometimes, good, sometimes bad and sometimes ugly. And the kind of choices you make, moulds you into the person you are and the life you lead. Sometimes a lot of choices we make are not really ours, we chose it because somebody else wanted us to. While that might not really be what you've wanted, that was probably the best and that's the beauty of naievity.
On the other hand, what if all the decisions you made, was exactly what you wanted? That sounds perfect doesn't it, but usually a decade later, you wonder if you had the choice to do things a little differently. Reverse, retake, Ctrl Z.... and if you didn't think that way, you are probably lying to yourself. That's just human nature, to want and to change.
