Pyromedic's philosophy: (my 2 cents worth)
Wealthy people don't pay interest unless the interest can be deducted as a business expense and what they purchase will earn them more money than what interest costs. They may or may not be happy and they usually have stress.
Rule: Debt = stress at some level.
Really wealthy people don't pay interest at all, they pay cash for what they want with earnings from investment capital. Their wealth is so great they will never want or need for anything they cannot afford, and they are happy and stress free as far as financial concerns. Poor choices due to great financial wealth may ruin their happiness and induce stress.
"Wealthy" is a relative term. Whether one is wealthy or not has more to do with whether an individual's wants and needs are satisfied, lack of stress and their happiness than it does with their net worth. A poor man can be wealthy if he has no debt, his wants and needs are basic and he has enough to pay for those wants and needs without stress or debt and is happy.
An average person can become really wealthy under the same conditions with the addition that he/she has funds above what he requires to meet the above parameters and invests them for a return. Simple and few wants and needs can be the key to the average person becoming really wealthy if that person is wise with their income stream and stays out of debt.
Anyone can be wealthy if they are willing to adjust their "wants" to a level their income can support without debt and they can be happy with it.
Take my "2 cents" and try to buy happiness with it. I can afford to give it to you.
