Yo,
I doubt I will ever have an earned income over 100k. Seriously doubt that, and put that number VERY high. However,. I do plan on retiring a multi millionaire. In fact, any person who makes a good 50k in W2 income should retire with over 1 million in savings without much trouble.
The only thing that is needed is good planning and delayed gratification. Do you know how fast money can grow if you will save regularly, and sacrifice to save?
