Конечно! Вот ваш текст на английском:
"I also found my job. At first, I had doubts, but now I am confident. I want to join the Ministry of Internal Affairs and become an investigator. I hope I succeed, so I am diligently preparing for the exams and going to the gym. As for my parents, they are very happy."
