Self-esteem & Insecurity

There used to be time when I wasn't confident at all. I was just a sack of tears, insecurity and fears. Saying that now I'm completely sure about who I am and that I'm satisfied with myself, would be a lie. A huge lie. No one is ever satisfied, because we're always trying to reach something more, to be anything more. Or anyone. Why? 

I'd say the reason is that we all have our own problems, troubles or issues, and we can never get rid of them. We need to fight the whole life against them. In my opinion a person with enough courage to fight can be labelled as confident. Insecurity is, on the other hand, when you give up, fall down on your knees and let the others to rule your life. But you can never say if you are self-assure enough, because self-esteem isn't a circle or a square where you start at some point and at some point reach the end. The point is there isn't any end. It's a neverending and always changing scale, line. 

This whole thing depends on someones personality. Some of us have the feeling that this is relevant, some not. Of course there are people who say that dreams, life targets or hope are useless and just for fools. In my opinion is this how the person who gave up looks like.
