How to start now and change your fate against the odds

Close your eyes
Imagine
You are yourself from 20 years in the future
Your forties self
Living a life of mediocrity
A family of three squeezed into a small house of less than 20 square meters
Your child can only attend the worst local middle school
Your spouse works as an ordinary cafeteria aunt
And you work night shifts all year round
Doing the most exhausting logistics sorting jobs
A few thousand yuan in dead-end monthly wages
Crushed by mortgage, life, and reality
Even having thoughts of suicide
One morning on your way home from work
An accident occurs
Instantly transporting your consciousness back 20 years
Back to when you were just in your twenties, freshly graduated
Heaven has given you a second chance to restart your life
So now, do you know what to do?
