We must realize that we are the ones who manage our lives and guide it in the right way from there. This does not mean that we must plan our entire life or every detail of it. So... why is it important to start planning now?
Because our lives will start from the direction we have decided now. Our future will be shaped by the decisions we make.
Also there are many paths in life, we can start a course and think about some questions, such as what values we will have, what types of friends we will have, and so on. As far as friends are concerned, they can influence us in many ways. In my opinion, there is not only one kind of friend.
We can have many friends, but we know when we should be with each of them. We can have friends to study, have fun, or both. This habit also applies to learning, because we can predict and be prepared to meet everything we have. If we have an exam, we can study a few days in advance.
