Salary is a weird one. There's no 'perfect' figure is there- I've just striven to make sure that what comes in exceeds that going out. At the moment, not so good as I recently lost my wonderful full-time job (£32,000 ish a year, 65-70 hours a week) and have been unable to find anything else full time so I'll be doing a 3 day week (£18,000 per year for a 30 hour week) and picking up extra babysitting etc as and when I can- because although the figure is HUGE- seriously, growing up in a desperately poor area even reaching min wage was beyond me- it won't cover my rent, council tax, bills.
The pay off for earning so much is that I have to live in an area that can employ me- I'm a nanny, so I live in a shockingly expensive part of Greater London. I pay over £1000 per month rent for my tiny one-bed flat, over £100 a month for CT! Then other bills, food, transport, and it's all gone. Now if I moved home and managed to earn £18,000, even if that was doing a 70 hour week, I could rent a decent 2 bed! But there are no jobs there, or very few, certainly in childcare.
I'm seriously contemplating taking my career in a different direction entirely- I'd love to get a degree, I'd love to feel I was doing more with my life. I'm looking into trying to get into university to study something in health, perhaps occupational therapy or speech and language therapy. I know I'd struggle during the course and after, I know I would start off on a lot less money but there would be progression- I've never, in my life, had a pay-rise or 'moved up the ladder', once you take a job that's it till the kids are too old for you or they move! I could also think about moving somewhere less expensive and widen that gap between what comes in and what goes out- I'd love to get rid of that 'helpless' feeling about money, that feeling that when a job ends (which is every year or so, I can't seem to keep a job!) my outgoings are so much that every penny of my savings will disappear in a couple of months and I'll be on the streets! It terrifies me.
