Put away $4 everyday to become a millionaire

If you have ever dreamed about becoming a millionaire, that dream is only about $4 away, especially if you are in your 20s.

Granted, that's saving $4 every day until you turn 65, but it's sure to guarantee that you can retire in style.

In his book "Smart Couples Finish Rich," financial adviser David Bach lays out a path to becoming a millionaire for everyone. If you're 25, that means saving $109 a month or $193 a month if you're 30, Kathleen Elkins and Mike Nudelman reported for Business Insider.

"Becoming rich is nothing more than a matter of committing and sticking to a systematic savings and investment plan," Bach wrote.

For most people, saving this much could mean not visiting the office vending machine or buying a drink when you go out.
