What is the meaning of a young tree is easy to straigthen but when its big its diffcult?

The phrase "a young tree is easy to straighten but when it's big, it's difficult" suggests that addressing issues or correcting behavior is easier when they are still in their early stages. Just as a young tree can be easily guided to grow straight, problems or bad habits can be more readily corrected before they become deeply rooted. Once something has matured or become established, it often requires more effort and resources to change. This metaphor highlights the importance of early intervention and proactive measures in various aspects of life.
