His paralysis from Polio

Explanation:

Former President Franklin D. Roosevelt was diagnosed with Polio in 1921 and became unable to use any of his muscles from his chest downward. He tried everything he could in order to get better so that he may still claim his promising future as a politician.

When it became clear that he was not going to get better, he accepted it and found ways to adapt to it. The ways he adapted to this called for much resilience but he managed. This experience made him more compassionate because he could feel the struggle of daily life through his own challenges.
