The path to early retirement isn’t complicated. It’s not easy, sure, but as with many things in life, the most straightforward option is often the most effective. And if you’re trying to figure out how to retire early, any millionaire will tell you that it all boils down to one simple concept: compound interest.

I’ve mentioned before that there’s no magic trick to becoming financially free – but this is pretty damn close.

And it doesn’t hurt that it’s also the same trick for you to potentially become a millionaire yourself one day!
