Consistent small savings compounded over the long haul would produce a lot more than you'd ever imagine.
But if you have to forgo the basic pleasure of life for decades, like having a cup of coffee a day, in order to become a millionaire, what's the point of having millions anyway?
And that reminds me of some old lyrics:
Someday, you say, you'll have your fun when you're a millionaire
Imagine all the fun you'll have in your old rockin' chair
You never go to nightclubs and you just don’t care to dance
You don’t have time for silly things like moonlight and romance
You only think of dollar bills tied neatly in a stack
But when you kiss a dollar bill, it doesn’t kiss you back!
