Rules and details result in conflicts and inconsistencies. Conflicts and inconsistencies make life less bearable, more confusing and error-prone.
When constructing a financial plan, or any plan for that matter, resist the inclination for precision. Your plan deals with the future and precision is, by definition, impossible. Precise prediction is an oxymoron. Anything could happen. Physicist Erwin Schrodinger postulated that if a thing is not specifically prohibited, it will eventually happen. So too with financial outcomes.
The future, especially the financial future is complicated. Even complex. We cannot intuit complexity. We know too few facts and little about their interaction. Complexity is fundamentally imprecise. Hear mathematician Lotfi Zadeh, “As complexity rises, precise statements lose meaning and meaningful statements lose precision.” Not exactly the stuff of certainty.
There are defenses.
Most of all, understand what you are doing and why. People have known for centuries that we must not make our lives over-complicated. In his book, Walden, Henry David Thoreau, has noted:
“Our life is frittered away by detail. Simplify, simplify.”
Mistrust plans that are complex. The complexity can easily hide their flaws.
