Life is an one-way road, from birth to death. Biological time is caused by irreversible biochemical reactions and genetic control, which determines that our road can only be from birth to death, one-way, one-way, we want a good road, we want smooth sailing, we want wind and water, we want to be safe and healthy, it is up to us to decide, our way is only one way, carry the necessary things, through every station. After all, to be alive is to walk well under your feet, and the rest is scenery. We can't go back to that station in the past, so we just need to seal it in our memory, don't look back, move forward, walk well in the present, and run to the next stop, or the terminal.
Do not think about the past, do not fear the future, walk under good feet, and focus on the good.
