While I'm a big fan of money-saving tips, I think they can only take you so far. It's like how you can always put on more layers of clothing in the winter, but you can only take off so much clothing in the summer...there's no end to the things you could spend money on, but there are only so many places where you can cut spending to the bone.
I have found it helpful to keep a log of every single penny I spend. I rarely go back and look at it, but just the act of writing things down is helpful to keep me mindful of my spending. At times I have also tracked every penny coming in, along with freebies/bargains that come into my life.
We are now at the stage where we are aggressively investing in starting small home-based businesses for ourselves--to boost the income side of the equation. And we are continuing to invest in learning new skills, so we can do more things ourselves outside of the money economy.
I like how Your Money or Your Life is goal-oriented. I think saving is much easier if it is for a specific purpose. Then you can ask yourself which you want more: Gazingus Pin A or Long-Term Goal B. And if you choose A, at least it was a conscious decision.
This reminds me of the book Refuse to Choose, by Barbara Sher. It is actually about managing time and projects and lifestyle (for people who have more interests than time to pursue them all), but a lot of what she says in it could apply to money as well. She says that it is ok to put a project (goal) on hold indefinitely or drop it entirely, if you lose interest in it, because maybe there is something better to do with your time (money) than painfully slog through something to the end. Some days, I need a chocolate gazingus pin more than I need to save for a down payment on a home. Obviously, keeping your finances in order is a more serious matter than choosing which hobby to pursue next, so don't take that too far....
She also discusses different lifestyles for freeing up time to pursue interests, like working at an easy day job to pay the bills, or only working six months out of the year. In my case, we've expanded our financial options by living in a relatively crummy apartment for now (with the side effect that we feel rich when we compare ourselves to most of our neighbors). Later on, we will probably be moving to an area with a lower cost of living. It's a matter of choosing what is most important to you, in both the short term and the long term.
Finally, our society puts a lot of social (and regulatory and legal) pressure on us to live a certain way, and to meet standards of living that aren't necessarily important to us personally. There are also a lot of financial parasites in the system, sucking away our money in one way or another. We live in one of the richest countries in the world, yet so many of us feel poor and financially insecure.
