Why do people clearly want to change but always stay in the same place?

Many believe that their obstacles are ability, resources, and luck; in fact, these are often just surface-level answers.
The real issue is that people, on one hand, yearn for a new life, and on the other hand, are desperately maintaining their old selves.
Because the unknown brings uncertainty, and even painful familiarity still makes people feel safe.
So we constantly find various reasonable explanations for ourselves: no time, conditions not yet ripe, the right moment hasn't come, or we lack talent.
But the essence of these reasons is not to explain why we can't do it, but to escape the responsibility that change requires us to bear.
Our greatest enemy is never external difficulties, but the fear of the unknown inside, and the avoidance of responsibility.
Many times, it's not that we lack the opportunity to live as we want, but that we are always using today's choices to maintain yesterday's self.
The biggest enemy in life is not external resistance, but the ongoing tug of the old identity on the new life.
That self who has long been accustomed to the past always pulls you back to the familiar track;
and true growth is not about defeating the world, but about repeatedly breaking free from the inertia of the old self.
