I'm only a year younger than you, and in the future, I plan to get a well-paying job, and buy a field of a few acres. Then I will have my dream goats, sheep, and chickens, including the cockerel that I can't have atm as I live in an urban area.
Farming can be hit by more than a few pitfalls each year. This year, in this relatively small country, we have had Foot & Mouth, Bluetongue and Avian Flu - all of which lead to compulsory culling with sod all compensation (according to them, my purebred, pampered pet hens are worth 40c each - enough to buy half a small chocolate bar) by DEFRA, our dep. of agriculture. That's not to mention that there were countrywide movement bans to try and prevent the disease spreading, which prevented animals from being sold at market. This cost farmers
millions and there was no compensation. Add to the fact that DEFRA wants to start charging farmers for things that farmers couldn't do anything about and DEFRA made worse.
There was also the wettest summer for 100 years, with mass flooding and entire crops being lost & livestock drowned.
All in all, an annus horribilis.
To gain experience, I work on a city farm. If you live in an urban area then there is more than likely at least one in your city - my city (with a pop of 500,000) has 4. I get to work with pigs, sheep, goats and poultry (which I really enjoy), and I don't have to pay for the feed costs or anything. In fact, there is a vague possibility that I could start getting paid soon. If there isn't one near you then you might be able to get a part time job on a "real" farm.
Another thing you could do is WWOOFing - working weekends on organic farms - you work in exchange for board and lodging on a farm.
