不念过往，不负当下，不畏将来，不忘初心。
This is the title of a Chinese article that starts with 500 words.
Looking back on the past, we may feel regret or disappointment. We may have failed in our goals, missed opportunities, or experienced difficult times. But these past experiences are just memories that we need to process and learn from. We cannot change the past, so it is important to focus on the present and the future.
When we look forward to the future, we should not be too concerned with what we cannot control. We should focus on what we can do, what we have control over, and what we want to achieve. We should also be prepared for the challenges and difficulties that may come our way.
However, it is also important to remember that life is not always easy. We may encounter difficulties and setbacks that we cannot predict. But we must not let these things discourage us. We should keep moving forward, try our best, and never give up.
In short, we should not forget the past, but we should also not let the future bring us too much stress. We should focus on the present and the memories that we have, and never forget the importance of what we are doing and what we want to achieve.
