Morgan Housel: A simple rule that’s obvious but easy to ignore is that nothing worth pursuing is free. How could it be otherwise? Everything has a price, and the price is usually proportionate to the potential rewards. But the price is rarely on a price tag. You don’t pay it with cash. Most things worth pursuing charge their fee in the form of stress, doubt, uncertainty, dealing with quirky people, bureaucracy, other peoples’ conflicting incentives, hassle, nonsense, and general bullshit. That’s the overhead cost of getting ahead.
