Some things appreciate in value the longer you have ownership of them. Strategically purchasing assets that you are sure will increase in value, is bound to build you substantial wealth.
That been said, there's something called "good debt" that you can use to purchase things that appreciate in value, as well as, are functional.
A "good debt" is when you invest in an asset that yields more than your initial investment.
For example, a student loan can be considered as good debt, since it helps pay for a degree that you can then use to secure a high-paying job!
