For example, a friend of mine was complaining that he had to work hard to afford a house. However, he was dead-set on a set of ideals and a location he wanted to settle at. Maybe part of that was preference, but it was clear that part of that was some sort of preconceived notion hammered into him by society and peer examples.
Instead, he could have aimed to buy a cheaper house in a smaller town while working/renting in the current town and just moved out. In my home town, even smaller houses cost at least 400K but there are plenty of nice places where the houses are 60K. So, buy one of those instead and move away once you've saved up enough...
By taking a month and seriously going through what's important to have a happy, "basic" life, most people will find things that they can give up, but that will make them happier in the long run. Like living in a certain neighbourhood, buying this or that, taking a certain number of vacations, having an extra child, a dog, etc.
Most people end up saving TOO much for retirement...and while caution is good, our society hammers this idea of an extremely consumptive lifestyle that these endless 9-5 jobs support.
