Forgive yourself

In fact, it's impossible for a person to be right every step of the way. If you make a wrong choice, then just accept it.
Don't always bully your past self; at that time, he was standing alone in the fog, feeling very confused.
If given the chance to do it all over again, with the experience and mindset of that time, I would still make the same choices.

We cannot stand on our current height to criticize our past selves.
Understanding the past without trying to change it, knowing that the future can still be pursued; even if we are lost, we are not far from the right path, and recognizing that the present is right while the past was wrong.
Recognize our shortcomings and strive forward, look to the distant mountains and keep moving ahead.
