1. Lincoln was able to achieve success because he was willing to struggle against his handicaps.
to achieve = to reach = to attain ( parvenir/atteindre)
to struggle = to fight ( se battre/lutter )
2. He suffered many setbacks and yet he finished at the top of the tree.
setbacks = des revers/ des obstacles/échecs
at the top of the tree ( idiome ) = en haut de l'échelle
3. Although J.K. Rowling had touched rock bottom, she decided to take up the challenge of writing.
to touch rock bottom = toucher le fond
to take up a challenge = relever un défi
