My best money advice is to aim to earn more.
People get so over-excited over saving pennies but don't realise all the time they've spent chasing bargains could have been spent learning a new skill or supplementing their income.
If you can clean, iron, garden, babysit, file papers, use ebay etc you've got a skill that busy people need and will pay for. These jobs are often cash in hand (so shoot me George) and therefore better paid than the stacking shelves/bar work roles that are now so hard to come by.
Or take courses so you can add more professional strings to your bow and charge for them. I know someone paying for their PhD by doing mobile manicures at the weekends.
And be aggressive about chasing pay rises. Be the indispensible go to girl and take on responsibility. Know your worth in the marketplace and be prepared to keep moving in search of opportunities.
If you're a high earner in an industry that relies on recruitment consultants, always ask for a minimum of 10% increase at your annual review, because your company will need to pay at least as much as that in recruitment commission. A lesson I only learned myself a few years ago.
Set aside a weekend every year to sit down with your OH and work out where the money is going. Two heads are better than one and it makes you feel and act like a team on your financial objectives, not fall into the roles of "the spender" or the "saver". DH and I discuss things like our mortgage/pensions/holidays/big one off purchases. It sounds geeky but it means we never argue about money because we both know the score and what we're aiming to achieve in the forthcoming year. Companies have an annual review, so should you.
Finally, keep a list of what you've spent each day on your phone and then email it to yourself. Makes accounts and expenses so much easier to keep track of, so you minimise "leakage".
