We're on 1 income, I choose to stay home with the girls fulltime. It's going to be like this until the girls are in school. So I figure the sooner I can make it work the better off Ill be.
Savings I believe is a MUST. We didn't have any for a long time. We did find it hard to build up as we needed every penny for wk to wk. My dad left me money when he passed so we are lucky 'in way ' as if we need it we borrow it, then replace it with paychecks
I would try my hardest to put away 100 a fortnight even 50! Its amazing how it can build. The trick would be not to give into temtation.

Also haircuts for me are a yearly thing a) the money b) the time!
