I will add that, being that I have a very clear view from the inside of the fishing world, very, very few ambitious anglers are able to make a career out of fishing, relatively speaking. Most think it's all about fishing and winning tournaments, and the money, sponsorships, and endorsements comes naturally with that success.
Total hogwash.
Fishing success is merely a minimal requirement. And, to be honest, fishing is a mere fraction of being a professional angler. It's all about your personality, preserverence, attitude, networking, business savy, and ability to market and sell products. A degree in business or marketing can be a huge benefit.
Becoming a professional angler is a long, tough road to haul. It's grueling, and takes years to finally break through. And by then, it will take years to dig yourself out of debt. In many ways, it's like getting a college degree. There are no shortcuts.
If nothing else, college teaches you to make a goal for yourself, and stay focused on accomplishing it. This is why many companies use degrees as a screening agent. They want people who can preservere and stay focused on accomplishing an objective. That's not to imply ONLY people with degrees can do that. But it's a simple way to screen people that way. This is why degrees open so many doors.
That said, a college degree will not make you smarter. I know and work with many people with post-graduate degrees that are dumb as soup. And plenty that are incredibly smart. The degree(s) didn't make them that way. Yet I've met plenty of folks fresh out of college who think they know everything they need to know about the job, and won't hesitate to tell YOU how to do your job. LOL! Oh man, if they only knew how green and niave they really are.
College degrees are merely entry tickets to your chosen field. What you do after you gain entry, determines your own success. Always remember that.
