Kevin, I'm currently in school at Virginia Tech and just switched majors to Fisheries Science...a large part due to this forum and other things. I was in engineering, making good money. I even had a guaranteed starting salary of 30-35k directly out of college working with the state DOT. But after two summers of internships and realizing that I would be spending 35-40 hours a week sitting at a desk staring at AutoCAD, I decided that this wasn't what I wanted to do for the rest of my life...
Here's what I think...
I always here people talking about things they wished they would have done (ie they didn't go to college, should have went into a different career, etc). I don't want to end up in their shoes 20 years down the road, so my philosophy has always been to never get 'stuck' in this position. If there is something you want to do, do it, whether it's bungee jumping or changing careers. Meadowlark has posted several times about how being a pond owner/manager is all about the enjoying the journey - from stocking fingerlings to catching those big bass or reaching whatever goals you have set. Life is the same - enjoy the ride.
So my advice...ask yourself where you want to be in 10, 20, 30 years and what do you want to be doing? Then do it.
By the way is anyone hiring summer interns in a fisheries related job? If so, please PM or email me.
