I started saving prior to University as I needed to pay for my university studies and refused to take on any debt. Thus, saving money as early as possible is something that I am a strong advocate of, and also passionate about. I always reference Burton Malkiel, the author of A Random Walk Down Wall Street. He describes the power of compound interest here: William, starts saving $4,000 a year when he is 20 and stops after 20 years, after having saved $80,000. His brother, James, starts saving $4,000 at 40, and does so for 25 years, for a total of $100,000 saved. They each earn 6% on their savings. At age 65, William will have $850,136 in his account, while James will have only $219,242. Despite having saved less, William's nest egg will be almost four times greater because of compounding. TL;DR: Start Early.
