Dividend growth investing encourages long term buy and hold investing. With dividend growth investing you buy a company with a rising dividend at the right price, and you then hold on to it for as long as the dividend is at least maintained. You ignore all the noise out there, and keep holding.
If you keep your emotions in check, you may find yourself holding companies for decades to come, while enjoying rising dividend income. This passive approach keeps investment costs low, which means that you get to keep your fair share of investment returns. It is easier to practice dividend investing through the difficult times, because you are getting paid to hold the worlds best quality companies.
With dividend growth investing, all we do is buy future income streams. With every $1,000 that I invest, I end up generating $30 - $40 in annual dividend income. This income can be used to pay for my expenses in retirement. If I earned $20/hour, I am essentially buying back 1.5 - 2 hours of freedom with every $1,000 invested. The goal is after several years of saving and investing, to replace your paycheck with the dividend income from your portfolio.
