Invest your time. For example, you might like having free time, so you give yourself a few hours a day to do nothing. But if you were to invest those few hours into getting rich, you could work towards having 20 years of free time (24 hours a day!) with early retirement. What can you give up now in exchange for being rich later? Investment advisor Dave Ramsey likes to tell his radio audience, "Live like no one else today so that you can live like no one else tomorrow."
