hi there
the key here is, what is your definition of a good living ??
this is entirely subjective, and vares from person to person, some people are happy at £25k per year, others at £10ok per year.
therefore this is diffcult to quantify.
i personally have worked extremely hard for my self for 4 years, employing staff etc, i was happy, but financially possibly not, now i have taken a Sales Manager role, that will earn me in excess of £60k in year 1, will put a brand new car on the drive after 2 years (owned ) i wont say i work less than i did for myself because if i work harder i will earn more, however i dont have stress like before, dont work weekends, have got holidays to take, and generally am a lot more chilled out.
therefore it can be said that i am happy in the role that i have got, as the combined income of the household is comfortable, including rental income from a property, and we do what we want to, with out major hassle.
that is why it is a subjective matter, others mya need more or less to be happy, you have to be content with what you do.
