Life is ever-unfolding.
The purpose of life is to grow, to become more, to evolve, to become richer and bigger.
When you put a seed in the ground and the right conditions are met, it follows its purpose: to grow.
So your desire to want more is natural.
More knowledge. More money. More wisdom. More action.
More is good if it is rooted in the natural purpose of life.
But to let your life grow, you need to meet it with the right conditions.
Just like a seed cannot grow without rich soil, sun, and water, your life cannot grow without wisdom, courage, self-control, and justice, all underlined with awareness of one's being and the world.
The purpose of life is to grow, and so is your purpose.
