If you’re tired of being broke, it’s time to take action. A recent email from a woman facing foreclosure with a 9-year-old child shows how critical it is to build financial security. My advice to her—and to anyone in this position—is threefold: Learn How to Sell: Sales skills are invaluable. Whether you’re selling a product, service, or even your own skills, learning how to sell is one of the quickest ways to generate income. Start with simple things—selling online or locally—and grow from there.
