People make an amount of choices in everyday life. There are some choices that people want to change the decision that they have made if they would have a chance. Let me share with you a difficult choice that I made before. When I was a college student,  I always was eager to take part in some competitions and wanted to win the first prize. Because I thought those experience could give me an advantage when I found jobs. There was a good opportunity that I had a chance to enter a national-level contest about international trade exhibition. So I just grabbed it as a team leader. I put my shoulder to the wheel for winning the prize, and my team members and I practiced a lot about the presentation. But the day of my final exam and the grand final of the contest was the same. So I had to attend the final exam rather than the contest. And several days later, I knew my team came the second in the competition. When I heard this news, I felt not only happy for my team members, but also regretful about my choice. Because if I take part in the final round, I would be one of the people who can share the results.
