Hi and welcome to TAS!

No-one on here will tell you your plans are ridiculous - many of us here are trying to do the same thing in many different ways and hopefully we'll all be able to help each other along the way. The reason we started the website was to help others avoid the mistakes we've made

BIG website!
If you're hoping to pay for three weeks in 5* luxury three times a year from your smallholding activities, you may be disappointed

Anyway, you won't be able to leave your pigglies for things like holidays. There's a thread in Coffee Lounge with a report on 8 case studies making a living from under 10 acres. It's quite interesting. All depends what you define by a living, I suppose. Our 12 acres wouldn't support our family, but we can produce a lot of our own food so reducing our outgoings and make a small cash income. We'll need an external income for some time to come though.
Enjoy - and we'll look forward to sharing your adventures.
