Abraham Lincoln said, “The sense of obligation to continue is present in all of us. A duty to strive is the duty of us all. I felt a call to that duty.”
And Abe didn’t quit, despite all the failures he had known in life. In 1816, his family was forced out of their home. In 1818, his mother died. In 1831, he failed in business. In 1832, he ran for the state legislature and lost. That same year, he lost his job. In 1833, he borrowed money to live on, and took 17 years to pay it back. In 1835, his fiance died. In 1836, he had a nervous breakdown and was in bed for six months.
In 1838, Lincoln made it to the state legislature, but lost in his race to become speaker. In 1843, Lincoln ran for Congress and lost. In 1846, he ran again, and won. He ran for re-election in 1848 and lost. In 1849, he sought a job as land officer and was rejected. In 1854, he ran for Senate and lost. Two years later, he sought the vice-presidential nomination and lost. In 1858, he ran for Senate and lost again. And in 1860, he was elected President of the United States.
Lincoln said, after one defeat, “The path was worn and slippery. My foot slipped from under me, but I said, ‘It’s only a slip, not a fall.'”
That is the key to success: not avoiding loss, defeat, and mistakes, but learning from them.
