I believe a big issue with many people is wanting more than they need.
I am not a religous person, so I am not coming from that angle.
I often hear,' that is a nice big bedroom, huge lounge" etc, it all costs money they may not have needed to spend.
I have written an article about good debt , bad debt and published widely.
It always creates discussion for obvious reasons,
I have a small home, but I can afford to race motorcycles as a result, that is one advantage of good, appropriate debt.
