We often think that when we make choices that they apply only in the moment and we can when we find out that we don't like the old choice then we can just make a new one. True but a very narrow perspective on the implications of making choices.
Each choice we make is of course the best one we can see at the time of making it which means that we will end up living with that choice until such time as we see that the results are not to our expectations.
There is no such thing as no impact from making a choice. A choice is a commitment to action on our part even if only a mental one. There is no going back to the past to start over as if the choice had not been made.
Choice is a powerful tool and we might even say that there is no such thing as trivial choices as each one changes our possibilities for future choices.
