This is what business school forgot to teach

If you've ever made a decision in the moment, and then later you look back on it and you're like, I had no idea what I was getting myself into. That's called opportunity cost, and this is lessons business school didn't teach you. So to understand this, let's say you've got a lemonade stand and you want to make more money every single day. Well, you could start offering chips along with the lemonade, and now 20% of your customers buy a bag of chips when they go to check out for their lemonade. Or you could just improve your marketing and double the number of customers you serve every day. Now, here's the thing. The cost of offering chips isn't just the 20 cents the bag of chips costs you or whatever it is. The cost is also that you're not making twice as much money from twice as many customers. And this is where you really got to take a step back and just consider, what else could I be doing with this time and with these resources, rather than just jumping into the first opportunity that presents itself?
