That programme you refer to is "Monty Hall's Great Escape". It's a lovely idea, but financially it doesn't stack up. E.G, he's shelled out £700 for some hens and a chicken coop that produce a few egs a day. The RIB he bought cost £1000's and he said he did £20 of fuel to catch a couple of Mackarel. I have no idea how much it cost for the rental of the solar wind energy unit, but it seems excessive for a couple of low energy light bulbs and a fridge. I'd have used a simple 12v solar charged car battery system for lighting and run a fridge on LPG, but then I don't have a BBC programme maker's budget!
It looks idyllic, but what makes me laugh is that he is eternally positive and so very enthusiastic about everything. I wonder how he really feels when the camera is switched off, it's wazzing with rain the novelty has worn off. Great entertainment though. I forecast that he will end up presenting some TV show like Ben Fogle did. Good luck to him!
I am sorry you feel down. The stress of unemployment is a tough one and I too had a career in IT. It's becoming a distant memory now so I am forced to consider other things. I have an aversion to risk and paid off my mortgage and built up some savings. Boring, but safe.
I know what it's like to be verbally offered a job, only to be let down later. It can be really tough, but the conclusion I drew was that I was better off not working for people who were prone to bullshitting about such a major thing. It was a business development role and I put this faux pas down to the fact I was dealing with a salesman and not an engineer. Who would you trust? Stereotypes always seem to be perpetuatued don't they!
By the sounds of things, you are better placed than many to get a shot at a decent opportunity. You might have to do some commuting or live away from home for a while, but i'm sure you will find something soon.
Good luck and enjoy the Leffe!
