“When we talk about investments on a personal finance site, we’re usually discussing things that you can buy for a certain amount of money that will, in theory, provide a return on that money. Stocks, bonds, real estate, porkbelly futures – you get the idea.

Such investments are a valuable thing to know about, of course, but it just scratches the surface of investing. You actually invest all the time, whether you realize it or not.

I prefer the broader definition of investing: an act of devoting time, effort, or energy to a particular undertaking with the expectation of a worthwhile result. That worthwhile result doesn’t have to be money at all – it can be a good relationship or an improvement in your health or anything else.”
