I'd suggest investing in a business (or businesses) of your own.
A successful business will provide you with the greatest return on investment you will likely ever come across.
There's no blueprint on how to do this - but there is definitely wisdom, strategies and tactics you can use to significantly increase your odds of success and maximize your ROI.
If you're interested in learning more - give me a call.
In any case - Best of Luck!
I agree with Naeem. Do some research in companies that you believe in, and invest in them. Invest directly or through good growth stock mutual funds. A gradual increase in your saved money every year will start generate that passive income that people talk about.
The stock market's average since inception has been around 11.5%. For example, if you were to have $500k saved up, and you are earning 11.5% annually that could yield $57,500 (500k x .115) which would be considered passive income.
