We have to be ready to accept our failure, to admit that we did not succeed in choosing the one we made, and to try again, because life is a series of trials, and it makes no sense to succeed in all of them. Every possible choice has its positive and negative sides, and each of us has to decide which one is the least bad for him, the one that he can bear the negatives.
Every choice has a price that we must be willing to pay, as there is no change in our lives for free, and the search for free options is a trick.
