## A Challenging Yet Rewarding Journey


Ahmed was preparing for his university entrance exam. He had studied hard day and night, and he felt nervous and anxious before the exam. His father encouraged him by saying, "Don't worry, son, the ball is in your court now. Just do your best and *break a leg*."

Ahmed entered the exam hall and began answering the questions. He faced some difficult questions, but he *bit the bullet* and continued until he finished the exam. He felt exhausted and tired, but he was happy that he had *let the cat out of the bag* and completed the exam.

Ahmed waited anxiously for the exam results, and when he finally received them, he felt overjoyed because he had *hit the nail on the head* and got the score he had hoped for. He had *paid an arm and a leg* in terms of effort and fatigue, but he had achieved his goal in the end.

After graduating from university, Ahmed got a good job and traveled to a foreign country to start his career. He faced some challenges at first, but he overcame them with his determination and perseverance. It was *a piece of cake* for him, as he didn't *beat around the bush* but faced the challenges head-on.

One day, Ahmed felt very sad after receiving bad news from his family. He called his close friend and shared his feelings with him, and his friend *was a shoulder to cry on* for him and supported him through his difficult time.

After some time, Ahmed's mood improved, and he felt happy again. He was *raining cats and dogs* with joy, as he had achieved a lot of success in his life.

Ahmed was *over the moon* with everything he had accomplished, but he never forgot his challenging yet rewarding journey. He learned from this experience that nothing is impossible if one puts in the effort and faces challenges with courage
