Translate the following English sentence to French:
"It is perhaps better to begin something late, but to begin with all the guarantees in place, than to find half way through that the studies have not warned us of some difficulty or other, meaning that we have to go into reverse, which would cause even greater delays."
Il est vaut mieux commencer un peu plus tard, commencer en ayant toutes les garanties, que se rendre compte à mi-chemin que les études n'ont pas prévu toutes les difficultés et qu'il faut faire marche arrière, ce qui provoquerait davantage de retards.
