I agree with both 2 sentences “you should not think about the past, stay in the present” and “learn from the past to improve the present and the future” The story passed into life with both happiness and unhappiness. I think in life everything that happened we can’t go back corrected. We can’t determine any life’s pathway so what’s wrong or the story in the past. was compared to learn and stay with it. When we can accept and see the truth about what happened. We’ll improve the past and be happy with everything in life.
