— Very good! You are a person who lives here and now, you are comfortable with whatever reality presents to you, and moreover, your happiness doesn’t depend on future conditions.

Then, 10 years later, they check the results of their SAT scores, their body index mass (yes, really), and educational attainment. Those who wait for more when…
