My wife and I, then 25 and 27, left banking and a building society career and bought a 6 1/2 acre smallholding in west Wales in 1981 with a view to farming it (2 hand milked house cows, half a dozen goats, some pigs, some sheep, chickens, ducks, geese, rabbits and, of course, bees - and we'd only kept guppies before
). We concentrated on getting families to stay with us in our 3 bed 500 year old farmhouse - eventually rented another 3 1/2 acres) getting the children to collect their own eggs for breakfast, some progressed to milking lessons on a kindly old goat we had and a very few older ones, and adults, on our gentlest cow. We made a really good living with families coming back again and again and bringing others with them. Admittedly we did sell them our beef, lamb, pork etc. and home grown organic veg at breakfast and especially evening meals (which you might not want to do) but it worked and we would still be happily doing it if not for ill health. It can be done and was incredibly rewarding.
