“Stubborn Attachments” by Tyler Cowen talks about some of the problems of financial decision-making across time. How do we balance actions and long-term consequences in guiding our choices?
Discounting cashflows is one way to take into account the “Time Value” of money. A Dollar today is worth more than a Dollar in 5 years' time. Making decisions based on discounted cash flows ends up almost ignoring 15–20-year time frames. The underlying assumption is you can reinvest at the end of the period.
I take the essence of his argument as a focus on Maximum Sustainable Return. Sustainability is key. You need endurance to make sure you are in it for the long run. To extend what you are doing to the next generation, and the generation after that. To adapt your thinking from 5-year plans to 1,000-year plans. Consequences beyond "you". Where BIG interventions fizzle, but small sustainable actions have big long-term effects.
Epiphanies, vanity projects, and conspicuous victories are much less impactful than small sustainable adjustments. “Most people overestimate what they can achieve in a year and underestimate what they can achieve in ten years.” (Amara’s Law).
Time is the most powerful investment force.
