The four key components (in my opinion) to playing at the collegiate level (and beyond):
1. Skill work - Practice your craft and practice it often.
2. Strength & Agility - One you get your mechanics consistent, get stronger and quicker through physical training.
3. Mental/Emotional - Train your brain as much as you train your body. Controlling your emotions, understanding the importance of confidence and learning the "Three D's" (Dream, Dedication & Discipline) are paramount.
4. Academics - You can't succeed on the field if you aren't succeeding in the classroom first. We are called student-athletes NOT athlete-students.
Are you or your catcher covering ALL the bases or just one or two? Follow your Dream (of playing in the big leagues?); Stay Dedicated and work hard on each component (work ethic); And finally, stay disciplined, avoiding all of the distractions that come with being a student-athlete (social life).
These are not in order of importance as they are ALL keys...
