With the start of the season comes the need to set goals. During this initial part of the pre-season focus the goals around fitness. Your short term goals need to be specific and measurable. For example, completing all eight 40m sprints under 6 seconds every Thursday. While this sounds like an easy goal, you will need a partner (or a video camera) to help you time yourself and you will need to bust your butt from certain starting positions to ensure that you achieve this goal.
Your goal needs to scare you a little bit. If you know when you set it you will achieve it then it is not big enough. An example from school, a student with a 3.0 GPA aims for all Cs. From past experience, this student should easily achieve this goal, however a goal of 3 As and 1 B is more reasonable and will scare the student who knows they need to work hard to achieve their goal.
