Remember when you were a child? When you were in elementary school, junior high, or high school, time seemed to go by really slow. Especially during the time when you were attending classes. A year seemed like it took forever. Now that you are an adult, the days seem to pass by more quickly with each passing year. A year doesn't seem like that much time at all now. I'm sure you can relate.
Why this happens is still a mystery. One theory is that when you were younger, a year was a larger percentage of your life. For instance, when you were 10 years old, one year was 10 percent of your life. However, if you are presently 50 years old, one year is only two percent of your life, and is less significant. This is one of the more common theories, but I don't agree with it.
From my own life experience, I can tell you why time passes more quickly as an adult. In fact, I can pinpoint the exact moment when time started going faster for me.
It was when I started paying my own bills.
