Even if you were to go to college, your learning journey would NOT be over! I've been lucky enough to have attended (and finished) college twice and I invest a significant amount of my own time, energy and money to continue learning new things, applying them to both my personal and professional life - over and over and over again, learning never stops!
For myself, what I've found helpful about college:
1. It gave me the basics of how to learn how to learn (and I continue to look for ways to learn new things more effectively). That was a natural outcome of taking classes, studying for exams, etc, etc.
2. It gave me credentials that opened the door to opportunities. There are some paths in life where having that college degree becomes easier to attain than others...and there are some that are completely excluded entirely (do you really want a surgeon that never went to college operating on you?).
So, you're not wrong to think that college isn't for everyone - it's not - but before you make that call, ask yourself WHY you would want to forgo that opportunity and make sure you're comfortable with your answer. And...ask yourself that question - regardless of how you answered it - often; remember that you don't have to make a decision today that you can't change your mind on tomorrow!
