I've been living economically for years in order to have money to travel. Some of my "tricks":
1) drive that car until it won't go any more.
2) use the library for reading material and movie DVDs.
3) eat out only occasionally.
4) buy some of my clothing at thrift stores.
5) think it over a few days before making any purchase of significant size; I often lose my enthusiasm for the item after a day or so.
6) consider going without some of the new gizmos; I use the internet and a pre-paid cellphone and have not invested in GPS navigation devices or the more complicated and expensive devices. I'm still considering whether I "need" one of the new fancy TVs.
7) save travel money by combining tasks when out driving; I can grocery shop and get my hair cut in the same trip, maybe even combine this with a medical appointment.
8) occasionally I put cash into my safe-deposit box to save for travel or other purchases; I am now saving for some much needed furniture.
9) give gifts, but on a modest level and only when I really feel like it; I skip most Christmas gift-giving.
10) donate selectively to organizations I know and believe in. I throw away most of the mail I get from charities.
11) make and drink coffee at home, mostly. Only occasionally I treat myself to a coffee at one of the shops.
12) give up soft drinks. For me, drinking a soft drink daily was a habit that I easily gave up.
13) find stores for less expensive groceries; I buy coffee, cheese, and cases of canned foods at Costco.
14) stating the obvious; I don't smoke and spend very little on alcoholic beverages.
15) I spend money on things that are important to me. I rarely feel deprived for "going without" a lot of these things. When I'm traveling, I know my economy is really paying off. I'm economical there, too. But that is another topic.
