Boris Pasternak said this quote

I am weary of this notion of faithfulness to a point of view at all cost. Life around us is ever changing, and I believe that one should try to change one’s slant accordingly—at least once every ten years. The great heroic devotion to one point of view is very alien to me—it’s a lack of humility. Mayakovsky killed himself because his pride would not be reconciled with something new happening within himself—or around him.
