Jesse admits he's got an itch to scratch. He likes to invest gamble in the stock market from time to time, using an app that allows him to trade at the swipe of a finger.   At least he's honest -- it's gambling with fun money, not investing. And that's the key. It's money he can afford to lose, and it's not much.   Sign up for a free 34-day trial of YNAB at www.youneedabudget.com   Also, go to https://www.youneedabudget.com/bootcamp/ to sign up for the YNAB Debt Bootcamp!
