1. Patience
Patience is one of the most important traits when it comes to saving money.
This means waiting until the first wave of product hype has passed, keeping a car [or av equipment] for an extra few years before getting another one and waiting until something you want fits into your budget instead of putting it on credit.
Patience is often the difference between creating savings and being in debt. Having the patience to wait until you find a good deal is a cornerstone of good finances.
2. Satisfaction
When you're satisfied, there is no reason to spend money on nonessentials. The sole purpose of commercials is to make you believe that buying a product or service will make you happier, wealthier, better looking or improve whatever isn't bringing you satisfaction.
People spend because they want to capture the excitement shown in advertisements. When you are satisfied with what you have and your life (not trying to live like those on TV), your finances will be in a lot better shape.
