I think it is all about finding a balance that suits your lifestyle. We have debt, lots of it, and some of our purchases may not have been well thought out. HOWEVER, we also have assets, lots of them, and we pay our bills on time, everymonth. We are not savers but we recognized that early on so we borrowed for our retirement savings. Here in Canada, for every $1000. you put in your retirement fund, you get back approx. $300 in tax refund. So it made sense to us to borrow money at bank prime (currently 4%) to get a 30% return via our tax refund. We then used our refund to fund the next year's RRSP, so we earned 30% return again, and so on.
It is important to plan ahead for your future, but it is also important to live life as best you can, because you don't know how many "tomorrows" you have. We try to find a balance, and even though we may not pay the debt in full, we can always pay our bills. Having said that, we do recognize that the we are paying a lot in interest costs, and have a plan in place to reduce our debt. Our gauge has always been our "Net Assets". Our assets outweigh our liabilities, and that is a nice feeling.
