Try

Success isn't the goal. The goal is to do the best we can.

One night, there was no water in my grandfather's home. That night, the children (including my father) went to sleep without preparing negel vasser water near their beds because there was no water. Their father, Rebbe Moshe Mordechai, rebuked them. "If there is no water, put the empty cup near your bed." In other words, do as much as you can, even if you can't do the complete deed.

Yaakov Avinu was born holding onto Eisav's ankle. Did he really think he was able to stop Eisav from being born? Once again, my grandfather, Rebbe Moshe Mordechai, replied that our job is to do. It doesn't necessarily need to succeed. We must try to do the most we can.
