There are people who think that they can learn better by themselves than with a teacher. Others think that it is always better to have a teacher.
I prefer to have a teacher.
Having a teacher will be good for your intelligence, education, and most importantly,
your future. If you study with a teacher and friends, you study happily and with interest. But, if you study alone, you feel alienated and not so interested.
We normally see the students who study with teachers. But, we can hardly see the students who study alone. It means, having teachers is better than not having teachers.
I think people who prefer to not have teachers are unusual people.
Thus, I think having my own teacher is better than not having a teacher.
Teenagers study hard because it's an important time.
If you want to study hard, You must have your own teacher.
If you want to become a jobless person, you study alone.
So, students must have a tutor.
