If eat that frog is a think for daily schedule, there is also such a thing for life itself. You just have to get a few things done as early in life as you can. Or you end up living for other people.
There is a wisdom in this. Most of the sayings in any culture are largely a distillation of a kind of civilisation darwinism. All it took people to survive big problems in life, distilled in neat statements.
(However they might still be a good idea. I don't know.)
It also depends on how you translate the 'traditional way'. For example, on the one hand, for most of history people had about one surviving descendant per person, ie two kids that made it into adulthood to have their own kids. [0] On the other hand, they gave birth to many, many more kids. Which of the two perspectives do you want to preserve?
Similarly, during most of the last few millennia most people used to have kids really late in life: they typically only had about perhaps 20 years or less left to live when their first child was born. Should we emulate that? Viewed through a different lens, people used to have kids really early in life: the distance in years between your own birth and the birth of your children was much shorter, too.
Of course, the above paragraph is just a long winded way to say that people live longer these days. But still: how do you want to translate past behaviour? It's a choice that's up to you.
[0] I'm basing that purely on the mathematical observation that population numbers have only gone up substantially in the last few hundred years. Thus replacement level fertility used to be the norm.
So for instance the Founding Fathers died at an average age of 72 including things like Hamilton being killed in a duel at 47 years old. Only 2 of them died before 60 - Hamilton and Hancock (who had health problems throughout most of his life). John Adams lived to 90, and Sam Adams/John Jay/Ben Franklin/Jefferson/Madison died in their 80s. In fact this mortality age of ~70 expands all the way back to at least the Ancient Greeks. [1] The Bible also references this in Psalm 90:10: "As for the days of our life, they contain seventy years, Or if due to strength, eighty years, Yet their pride is but labor and sorrow; For soon it is gone and we fly away."
All the advances in medicine over the past millennia have dramatically reduced childhood mortality, but its impact on people who would have already made it into adulthood has been relatively small - perhaps 5-10 more years of very limited quality.
