The easiest way to save money is to stop spending them
Spend only on the essentials like food, housing, transportation (by transportation I mean if you drive don't lease expensive vehicle - buy/finance reliable car that won't need too much repairs), clothing and no luxury items. Don't renovate your home if you don't really need to, don't buy new TV if your old one still works and so on. Trust me, you will save money if you do this
