If you believe in these then there is no way that you won't believe in their direct opposite. Central to building self confidence is one's belief in himself. Whatever you set your mind to believe will all be taken as factual. Thus, you only have to manipulate the values that you would like to acquire. But what defines that "best" would be largely dependent on how the parent was raised in return. Major contributors would also include the events that has passed by during the time by which the child is being raised and the models to which he has learned to associate his realities. We were all born and raised in virtually dissimilar settings. We were all gifted with talents and skills and beauty and wonder along with the gift to use or disregard them. But once we recognize our potentials, we will find that life has more to offer than mediocrity. We have to understand though that there are a couple things that we are limited from. But these are compensated by the fact that we carry the potential of excelling on other things. People may point us to our direction but without our willingness to drive us there, no amount of help can truly help us except when it comes from our self. Self motivation will greatly affect the ways by which we build our self confidence. Unlike the detrimental habit of saying- "my life is messed up" or "my life is nothing but a good way to kill time", you can use positive reinforcements and say otherwise. We are then responsible of intensifying this fortress as we age. Being unable to do so is a form of disregard towards the precious gifts that accompany self confidence. If you failed to develop your self confidence as a child then think of it as a loss that you must learn from. Now, all you have to do is to muster all strength so you can start anew. There is no such world but because men tend not to listen to the voices that encourage them to believe in themselves, this world came forth to life. The thing though is that experience and time are often good teachers, if we truly take them as such. We will live with ourselves for as long as we live with them.
