One of the easiest ways to get exposure to dividend stocks is to buy ETFs like DVY, VYM, and NOBL or index funds. You can also pay an algorithmic advisor like Wealthfront to automatically invest your money for you at a low fee. In the long run, it is very hard to outperform any index, therefore, the key is to pay the lowest fees possible while being invested in the market. Wealthfront charges $0 in fees for the first $15,000 and only 0.25% for any money over $10,000. Invest your idle money cheaply, instead of letting it lose purchasing power due to inflation. The key is to invest regularly.
