Note: as in the previous essays, this is a draft as I hone some of this content. Also, since I view these essays as consolidating and integrating what I've learned about ret-fin so far, I will continue to add to and update this provisional latticework over time in response to new findings or errors.

Life can only be understood backwards; but it must be lived forwards. -Kierkegaard
"Irrespective of the investor’s initial portfolio management elections—‘buy-and-hold,’ ‘constant-mix,’ ‘floor + multiplier,’ ‘tactical asset allocation,’ ‘bottom-up security selection,’ ‘top-down strategic asset allocation,’ ‘glide-path,’ ‘passive investment management,’ ‘active investment management,’ ‘benchmark relative,’ ‘asset/liability match,’ etc.; and, irrespective of the initial elections for withdrawal management—‘rules based,’ ‘fixed monthly amounts,’ ‘percentage of corpus amounts,’ ‘longevity relative,’ etc., the critical objective is to assure that the portfolio can provide the required cash flows. Investors spend cash—not Information Ratios or Merton Optimums; and they need to know that the portfolio can sustain a suitable standard of living throughout their lifespan. The need to know whether the portfolio is in trouble is a primary justification for establishing an appropriate surveillance and monitoring program." -Collins (2015)
