Find someone you can look up to. Then, learn from them. At the University, you may be able to connect with professors, students, alumni, and/or industry professionals. Having someone you can directly gain guidance from is extremely valuable. In addition, they often are willing to share their established networks when the time is right.
Experience comes with time. When you’re a college student, experience is severely limited. I’ve been connected with multiple mentors along my journey that have passed their experiences and wisdom down to me. Each one has played a large role in directing my path. During each growth stage of the business, from conception up to working with NBA players, a specific mentor played a key role in each step. It started with my family, grew to my professors, then expanded to include industry professionals, and even reached the "Worldwide Wes" level (Google him).
Moral of this story: To be the best, learn from the best.
