For me you can save money by self discipline. It is the most effective strategy to apply.  Look if you have self discipline with you you can cast out the beer in the table, expensive foods in the restaurant, travel without any good purpose, give to others without the proper way to budget the money. Without discipline everything that yours will be not yours if your attitude is not good. Save money as long as you can and while money is there looking at you. Also treat yourself sometimes if you wants to reward yourself by doing so.
