My biggest regret about my college/university time is not having expanded my breadth of experiences. In your teens and twenties you are at a point in life when you have not made too many decisions that set you on a particular path. It is an oportune moment to explore the vast buffet of life. As one gets older you find yourself moving in a particular direction and generally self-limit your own ability to deviate too far from the area you currently in. Add in the sunk cost fallacy and most people just continue the inertia of their early decisions.

Expose yourself to everything you have the least bit of interest in. Go to all kinds of group meetings, sign up for classes that seem interesting, talk to people that are different from you, etc. It is very likely you will never have such easy access to these possibilities ever again.

Do not believe that you must declare a major immediately and that it will be set in stone for the rest of your life.

TLDR: explore your interests without fear
