During the 1976 Summer Olympic Games, Japan's Shun Fujimoto won the gymnastic's gold medal for making a flawless routine and a perfect landing - on a broken right knee.
When asked, he said that the pain shot through him like a knife. "It brought tears to my eyes. But now i have a gold medal and the pain is gone."
Pain is only temporary. But the benefits last forever.
Same goes to learning. The process is undeniably long and difficult. But in the end, the reward is everlasting. As Imam Syafie put it, "If you can't bear the pain of learning, you will suffer the pain of being ignorant." :)
