For the first few years after my first wife left in 1978, taking with her half the value of the house I had paid for, a 1966 Fiat 500 and an Alfa Romeo 1971 1750 GTV, even though I was the foreman of a Mazda Dealership as I was single again I was taxed at the then current 30% income tax and living off black coffee and spam sandwich's, so going self employed in 1982 was a definite step forward.
You obviously need a good sell able skill,for which I whole heartedly thank my mum for saying "get yourself an apprenticeship and you will never be out of work" (two weeks unemployed since 1969 and that was me jacking a low paid job in) that and having a good accountant who really did his job well, unlike those that type your details into a program and tell you to pay the tax man £XXXX !!!
So life is never perfect, surviving these days is more than many can do.
If I carry on like this everyone will be putting nooses around their necks.
