This seems true, but obvious. I'm not sure that I buy that fiction promotes this idea: IMO, fiction usually glosses over how the characters got their powers because it's boring. Some real-life examples of power for cheap would be very useful. Here are some suggestions:

• Stick your money in index funds. This is way easier and more effective than trying to beat the market.
• Ignore the news. It will waste your time and make you sad.
• Go into a high-paying major / career
• Ask for things/information/advice. Asking is cheap, and sometimes it works.

Anyone have other real-world suggestions?
