Motivational factors aren't always external. In fact, it can be argued that the most important types of motivation are dependent on how we see ourselves. Self-evaluation and reflection are becoming increasingly potent in our modern society preoccupied with Facebook, MySpace, personal blogs, and other forms of self-expression. One's sense of self-- their likes and dislikes, their goals, needs, and desires-- shapes who they are and what they do. Naturally, it can be said that outside influences have a profound effect on our behavior and motivations, but as the clip below suggests, intrinsic motivation should be our real driving force, because at the end of the day, we only answer to ourselves.
