Scott Adams, the author of My Life Where Everything Goes Wrong, makes one of his core points: Most successful people follow systems, not goals. Why do you say that? Most of us have experienced the cycle of struggling to achieve a goal, only to lose sight of it when it lands and then fall into empty and confused thoughts until a new goal appears...... Emotions can fluctuate, and the gains and losses of a city are often very important.
 
The concept of system construction is a kind of probabilistic thinking, the core of which is to do a certain thing continuously in the most labor-saving way for a long time, and build a subsystem of its own in the long run, so as to increase the probability of success. This subsystem can be a writing system, a learning system, a fitness system or a diet system, etc. As long as it is not at the table, the subsystem has the opportunity to develop into a career, or even become "SOMETHING BIGGER THAN URSELF" in life.
