I agree with everyone here... we need more herp vets.
I have the same goal, man... to make a living breeding herps, but also doing other things on the side - T-Shirts, terrariums, supplies, maybe open a couple of retail stores. It's a good goal to have - but in the mean time, I'm working in the Information Technology field, so I'm not ever going to depend on my critters for my income.
Remember, having goals is great. Making sure you can live to achieve them is even better.
