I work 37 hrs a week (+ or -) for a Local Authority - but I run 2 businesses as well
1 - repairing computers - i tend to find that satisfying as its sort of problem solving
2nd - I carry out building thermal calculations for new builds and extensions etc - thats the one that allows me to run the car
to switch off - I clean my car, the wifes, the father-in-laws
unfortunately - doing effectively 3 jobs I have very little spare time, but thats ok, because I HATE sitting down and doing nothing - i even struggle to sit still and watch TV
