Get an IT job in the defence sector (or Home office I guess), get DV clearance and a few years of training/experience. Along with about a 10k pay rise on what you have and usually a much more relaxed environment.
Companies pay loads of money just for people with high level security clearance, even if they aren't all that experienced. It allows them to bid for the big bucks government contracts and stay onboard the gravy train.
That Man of Honour tag to the left is because I wore the t-shirt for many years and spent a lot of time in OCUK from the day they opened buying parts for other peoples PCs.
Somebody touched on it above but I'll expand:
If you bought a PC from a shop you wouldn't go back after 8 years and start complaining when the motherboard burnt out but being an individual making money on the side, people will come back 8 years later demanding I fix it for free.
The 8 years one was the longest but there had been others so in 2007 I finally decided to stop but even then I had one knocking on my door about 3 years later moaning about his PC that had crashed and it was all my fault.
For the same amount of time I don't offer help either to family or friends, once you touch their computer you become involved for life.
I see other people say the same yet I have been doing home pc's for 15 years and never had that issue.. Was turning over quite a bit at the peak died of loads in the last few years now Internet works and w10 / newer hardware is much more reliable and virus' are so rare
