Unexpected one-time income. Sometimes money falls in your lap, like a birthday gift, a tax rebate or an unexpected freelance contract. Believe it or not, I don’t encourage you to save all of this money. Instead, whenever I receive money I didn’t expect, I use 50% of it for fun – usually buying something I’ve been eyeing for a long time. Always! This way, I keep motivating myself to pursue weird, offbeat ideas that may result in some kind of reward. The other half goes to my investing account.
