Coming from someone who is 24 and in his third year of law school (7th year post high school), if you ever want to take a shot at it, now is your time.
I wish all the time that I had tried it right out of high school....given it two years and then gone to college if it didn't pan out. I still have dreams of fishing for a living, but I will now have to work for a pretty long time just to pay off the loans on school. And realistically, by the time they are paid off I will have a wife and kids and a job that needs me there 50 hours a week.
You have very little holding you down at the present time I assume (no wife, no kids, no mortgage). If you really want to fish pro, why not give it a year or two? I AM NOT SUGGESTING FOREGOING AN EDUCATION. But college will always be waiting for you (as will a wife and kids).
It takes a LOT of money to fish BFL/Stren/FLW or BASS in entry fees, travel, gas, hotels, equipment etc. etc. etc. But the way I look at it, during these winter months one could work two jobs and save every penny of it. By the time the season rolls around you would have a decent bankroll to work with, at least enough to get you through the season.
Just one man's opinion. You only live once, live your dreams,
