Toscanini and patient work
Before Arturo Toscanini was one of the world's great musical directors, he was a cellist so nearsighted that he memorized his sheet music. He also memorized the parts for every instrument in the orchestra.
One night when the conductor fell ill, Toscanini alone knew the entire musical score. With no advance notice, the 19-year-old cellist stepped in and conducted the entire opera from memory. He earned a standing ovation and was made permanent conductor. In a single moment, a near-sighted cellist's hard work overcame his own bad eyesight and propelled him into the limelight.

Not only so, but we also rejoice in our sufferings, because we know that suffering produces perseverance; perseverance, character; and character, hope. And hope does not disappoint us, because God has poured out his love into our hearts by the Holy Spirit, whom he has given us.(Rom. 5:3-5)
