I'm a millionaire now, but if I could give my broke younger self advice... Here are 8 big things I wish I knew sooner: 1. When you're young, your greatest gift is your age! Older people (wealthy people) love to see young people excited about building wealth... so find older, wealthy mentors and become their mentee. Draw close to them. 2. Stay out of debt unless it's a rental property mortgage that's rented for way more than the debt payment. But definitely get into this kind of debt.
