@ana1234 - I know a lot of people who fancy themselves as small farmers, but wouldn't have the first clue how to take care of livestock or grow a crop for sale.
If anyone is interested in learning the farming trade, particularly organic farming or permaculture, I would suggest they try a stint with WWOOF (Willing Works On Organic Farms) which is an organisation that will match volunteers with organic farmers to work in exchange for room and board. It's a great way to travel, as well as a very good way of learning the ropes on a farm if you're completely new to it. It might be harder than you expect.
Another option is to take a course in agriculture at a university or community college. Most of the time they are relatively practical and will give you a good grounding in the business and science side of things as well as allowing you to learn all the skills needed on the ground at a farm.
