Really can't tell you my earnings, and now I'm married paying childcare etc. When I was single I worked 6 days a week, 13 hrs a day I paid my mortgage, drove a brand new car, owned a motorbike, had 2-3 holidays a year, wore designer clothes, but I lived to work, all I did was work, work, work, so they were the things I spent my money on rather than clubbing every night. Outgoings again that all depends on how busy you are, more work, more outgoings. I am registered with HMRC as self employed, pay NI by direct debit, have a pension, critical illness, public liability insurance and an accountant.
Don't think I've missed anything out, it all sounds confusing but it's easy when you know how!
