To be certain is not only an admirable trait but also much needed in order to achieve success in any endeavor. Being certain gives the individual drive and a sense of purpose that will greatly aid in the journey. Recall the time when you are so sure about something. Did you remember the sense of power you get from it? That incredible feeling of knowing what you are meant to do and how free it made you feel. A clear mind and soul. One who lacks certainty seldom receives the support of others. No one wants to follow a person who is not sure of what he or she is doing, unless circumstances where the element of trust or failing in a group factor is in play.
