Reunion with my friend in my junior high school days was held today.
16 years ago, both I and he aimed at becoming a doctor, and we believed that we would be able to.
But, when it comes to entrance examinations of college, we couldn't pass the exams(Strictly speaking, he gave up taking entrance examination of medical department).
Now, we say "It was better for us not to become doctors. That's because we wouldn't have much time to enjoy ourselves."
So, if you want to be a kind of occupation, you have to reconsider whether or not it's suitable for you by learning pros and cons of the occupation.
