You’ll find that most people are too busy working to ever tinker with investing their hard earned savings.
The most important part of working is taking the time to make the investments. It kind of like playing poker, it will cost you to learn, and then it becomes fun and you get skillful.
If you take the time and choose a field of investment and have a plan, you won’t have to work the rest of your life. The guy investing your money takes his cut off of the top, and thats true even if your investment lost money.
The trick is not earning money, the trick is holding onto it, and making it work for you.
