Sometimes you’re just saving for a vacation (idiotic thing to do in my opinion), sometimes you’re saving for a house, and sometimes you’re just saving to build up wealth — in each circumstance, your time horizon is different. If you fail to take your time horizon(s) into account when investing your money, you’ll fail at investing. Don’t make the foolish mistake of thinking all investing is the same because investing for different time horizons requires different tools, techniques, and mental frameworks.
