Greed, being a powerful tool, usually leads to self-improvement and improvement of the world around.
Every person strives to have much more, regardless of what he has at present.
People want not only financial gain, but also more friends, spiritual enlightenment, or a new life.
This means that a person improves himself and thereby improves the world around him.
Sometimes greed can lead to negative consequences, including pain, death, hunger, and disease.
Therefore, greed can be a strong motivation that pushes one to improve one's life, and it can be a disaster that ruins one's life.
Greed often clashes with a person's other interests or desires.
Usually what you want most wins, so greed can lead to growth and improvement.
When you realize that certain desires are harmful to your main goals, you replace them with more useful ones.
It turns out that you fight one greed with another, which is stronger. And, strangely enough, it works.
