Still, many people need more than that to retire, let alone feel flush in retirement — so over time, that $500 monthly investment needs to increase. The best ways to do that are by investing any windfalls you receive or — better yet, and — increasing how much you save by 1% or 2% each year. A windfall might be any influx of cash you receive infrequently, such as a tax refund or employer bonus.
The folly of youth is believing that there's always enough time for everything. Youngsters often believe that retirement, or wealth building, is something that comes later in life, and are more preoccupied with the concerns of the now. Unfortunately, this often leads to a cycle of "Oh, I should do that next month," month after month, until before you know it, you're 10 years older and you've missed out on a decade's worth of compounding interest. The first step is to stop procrastinating; saving and investing is scary, but the longer you wait to do it, the fewer advantages you have.
