General inflation typically refers to the tendency of goods and service price levels to increase over time. Basically, one U.S. Dollar will buy you fewer loaves of bread than it did when your parents were born. Personal inflation is a subset of inflation that looks at our own (often rising) personal consumption choices over time. The general assumption portrayed by society and economists at large is that we need increasingly more (often higher priced goods) as we grow older. As we will see, we often have a lot more control over our personal rate of inflation than the economy at large.
The bottom line is that inflation in developed countries is overrated for efficient people and early retirees. In fact, I would make the argument that we can actually train ourselves to utilize our income more effectively as we gain more life experience. As we age, we gain a much better understanding of what our wants and desires truly are. We get better at understanding what is a need versus a want, and what luxuries actually make us happier. In addition, with a few lifestyle changes, we can position ourselves to maintain constancy while our peers’ personal consumption drastically increases over time.
