I will try to identify the rare cases when I have not had direct experience in what I am writing about. This means that the items that I'm writing about I am certain as to the value that they will provide you if you follow them. With a significant caveat. That caveat is that there is no situations that happens the exact same way twice. Therefore every situation and every encounter will have different permutations that could require different thoughts and ideas. To the extent that this happens, you must use judgment in using the advice put forth here.

— from Before Takeoff (front matter) · Hebrew Ethical Wills by Israel Abrahams

In the book

Where my advice touches your relationship with God, I have kept it light, only because I never considered myself the expert there; my experience is in the other arenas, and that is where I can actually be of use to you. And remember that no situation ever repeats itself exactly — every encounter arrives with its own permutations — so whatever I hand you, you must finish with your own judgment. I will admit, too, to a fear: that I haven't always lived up to the very ideals I'm setting down for you, and that you, or I, might hold that against me. — Before Takeoff (front matter)
