I honestly don't believe you're ever truley content with what you have; not if you're self employed. There's always more work to be had and when you get it you want some more.
You start off by thinking," Right, I want to be earning £500 per week".
Then you get there.
Then you invest in WFP, carpet machines, power washers, whatever, and now you reckon, with a bit of work, you can break through the £1,000 per week barrier.
Then you get there.
And so it goes on.
Even most smaller, sole operators wont turn down new customers when approached on their rounds.
Personally I've reached a level where the bills are paid each month very comfortably, I don't have to worry about nasty letters popping through the letter box, we're able to take the family abroad two or three times a year and we've always money available for extra such as eating out, rainy days, etc.
BUT ................................................
I still want more.
There are always more holidays to be taken; or simply longer holidays. I'd like a nice boat to fish from, the wife would like to trade in her soft top XR3i for a Porsche Boxter and so on and so on.
I honestly believe that in any business if you stop you just end up going backward
