Warren Buffett has said the best investment you can ever make is in yourself. The math supports it.

A skill that earns you $10,000 more per year for 20 years is worth $200,000. No index fund matches that on the same capital.

The Highest Return Self-Investments

  • Skills that increase your income. Coding, sales, writing, public speaking, financial literacy.
  • Health. Energy is your most important professional asset.
  • Network. The people around you determine your opportunities.
  • Knowledge. One book per month compounds into a significant advantage over 10 years.
  • Identify the one skill that would most increase your income in the next 12 months.
  • Allocate budget and time to developing it — treat it like a bill.
  • Measure the return annually.
