Why people invest — and why cash under the mattress ages
Light and non-advisory: inflation, time, goals, and why “doing nothing” still does something to purchasing power.
The story of the bun that got more expensive
Imagine tucking a banknote into a drawer “to be safe”. Years later it buys fewer buns, tickets or rent. That is lost purchasing power — often tied to inflation.
Investing (broadly) is trying to make money work alongside you — in securities, funds or other assets. It is not a profit guarantee. It is a trade: potential return in exchange for risk and uncertainty.
Time is a quiet accomplice (or ally)
A long horizon gives room for short swings to “blur”. A short horizon (you need cash soon) can turn a normal swing into a problem.
That is why beginners often start with “what and when will I need this money for?” rather than “which stock is trending on social media”.
Goal > fashion
Investing without a goal is like driving with no destination — you can go fast and still not “arrive”. A goal might be a cash buffer, housing, retirement, or simply “keep purchasing power”.
When you track a portfolio, figures like ROI or XIRR only make sense against that goal and what you actually contributed. They are not magic wealth buttons.
