What is the single most effective piece of financial advice you've ever received?

My grandfather retired at the age of forty years old, and lived a very extravagant lifestyle. Often he would tell me, make your money work for you and you won't work at all.

My grandfather did a lot of investing and was an avid angel investor. He was a fan of going to public executions. He simply loved them. He would often research about new devices being developed to execute prisoners and criminals.

He would then go to the executions to see how well his money was being spent. I think his insistence on investing in his passion is what gave him an almost unstoppable drive. Anytime he would hear about a new device or process being created that would be used in an execution, he would instantly become excited and try to get in on it.

My grandfather is the man on the far left holding a white hat and smoking a cigarette in the photo above.

Before he passed away, he told me that this country is going to probably go down the drain due to liberal policies trying to make executions more humaine. He said that this move would stifle economic growth for those in the execution industry.
