I came across at terrific post on Wisebread on giving advice to your younger self. Will Chen made this insight:
Don’t develop a tunnel vision about “what I want to be when I grow up.” People change careers all the time. Some of the most fascinating and successful people you’ll meet are doing something completely unrelated to their college majors. Keep an open mind. Audit a bunch of classes. Extend yourself. Learn things that are of interest to you instead of focusing purely on what you think will become useful to your career later.
My own experience fully confirms this concept. Pursue anything you find interesting. Get to know people from all walks of life — not just ones you think will help your career. You never know how these experiences and people will help you later in life, but they probably will.
By developing an interest in everything, and you’ll find life a much richer experience.
