Question

Write an essay explaining whether learning always has a positive effect on a person's life.

Answer 1

Although there are various options, here is what I would write if I were in your position:

Learning tends to have a positive effect on a person's life in that (1) by learning, one gains a sharper sense of what one does not know and is so able to ask more pertinent questions and (2) by learning one gains insight into diverse perspectives, and thus the ability to reframe problems and possibly gain fresh insight into these problems.
