For me financial freedom is not having to think about money. That means having enough to live how I want (which is fairly simply, but able to buy treats, or travel, without worrying about it) and also not having too much (which I then have to invest, make sure no-one steals it, ensure it doesn't lose its value etc).
I heard somewhere that being rich is having $5 more than you need each month, being poor is having $5 less. So for me financial freedom is having that $5 more. And the rest can go hang. Lindsay
