If nothing else, after stability is reached on a retirement income, you may find that is the time you have the opportunity for action on projects and ventures under the most favorable terms of your life.

So many things that really do make money but were not worthwhile on shitty terms can come into reach, plus anyone involved can have no doubt that you're intending to make something happen sooner rather than later. Whether it's building a desirable acquisition target, or laying the valuable foundation for a growing institution.

That's very true: the opportunity cost of most business projects is effectively zero once you are retired, so you can pursue something only marginally profitable that you enjoy and it counts as a win. In fact you have a competitive advantage against a 40-year-old with a young family to support.

The corresponding quote to:

  Youth is wasted on the young.

is:

  Wealth is wasted in the hands of the old.
