Agree that one should maximize networking, but college is not required to do so. Find like minded people where ever you are, always be seeking opportunities (learning, revenue generating, and all others) and avoid credentials and their associated costs. Be able to get the work done, learn how to when you can’t, and be enjoyable to work with, that’s most of what a job is.
This is my experience too. I haven't exactly avoided credentials as a principle (I have a BEng), but I totally agree with "Be able to get the work done and enjoyable to work with".
Do a good job, be secure in your abilities, have empathy for others. I'm a freelancer of 13 years with a lot of happy clients and – before I started living off-grid – I'd earn a month's rent in half a day. Now I don't have rent or mortgage.
Sure, I haven't climbed any corporate ladder, but I hope that in a decent company you can be those things and also do well.
