When you see yourself succeed, you develop more confidence in your ability to succeed at bigger and bigger things. This is how motivation works. When you set a goal, a gap is created between where you currently stand and where you want to be (i.e., you goal). That gap flips on a psychological switch called self-regulation, which is our way of evaluating how we are doing compared to our goal. If we are not performing in a way we believe is required to achieve our goal, we reallocate our motivational resources toward that goal. Thus, we can get a huge surge of motivation!
