Strange. I find it easier to save than it is to make more. If I really want more money, I just don't spend as much and, poof, the money is there! In fact, I try to do that as often as possible.
Of course, I also work full time and take on any overtime I can get my hands on. But then, I kind of like my job, so I can't say that's difficult either.
However, I don't think any of this will beat Ima's method. "The easiest to get more money? Why, I simply make my husband work more!"
