Just like opening sesame to open a treasure, sometimes at a certain critical point in time and space you can open the door to the past and start over. At that time, you didn't know who was giving up the opportunities that you could work hard to obtain again and again during that period of youth. However, you were sailing against the current, and if you didn't advance, you would retreat. You had to let go and struggle at the forefront of evolution in order to survive. You have to run as hard as you can to keep yourself in place. Only go faster and faster to watch their crazy lives trying to survive behind you.
