Your absolutely right, that is where the money is, no doubt. But money isn't everything, although it is nice, that's for certain...there is a lot to be said in doing what makes you happy.
As you get older you will learn that being happy is more important that monetary rewards. You won't be happy if you finish law school, but miss out on the progress you could have made in BB. Make sure you balance out the positives and negatives before you jump in to it. For me, gymtime and lifting are important enough that I wouldn't choose any path that took all my time. I get too much from my lifting to ever cut it completely from my life. It's more than a hobby, it's one of the few things that actually makes me happy in this world.
Total fullfillment is what life is about.........not a degree or money.
