I don't sleep well if I don't have enough debt?
Why do I say that? The very basis of the investment mindset is to make your money work harder than you! If you have money which is not used isn't it losing its value by the seconds? Lets see, inflation decreases the value of money at around 4% a year.
Personally, I subscribed to maximum leverage, dangerous some may say, as R. Kiyosaki says, dangerous is in the uneducated mind. Take Action and learn and be educated. When you are ready, you will feel that you may not have enough debts.
Have fun investing.
