There is nothing wrong with tenses. However present parti heading a clause is often used for particular events and preterite is preferred for general situations no matter the tense:
In your example,The young generation refers to a general phenomenon.
general: I walked a great deal, and thought about the coming year:
specific : I walked down the street, thinking about the future.
That might be the reason why your teacher corrected you.
