Goal, What is this?

Goal, a word, which we all love and think that it makes our life more meaningful. Starting from our childhood, we are asked to have some goal in life. The goals keep on changing but continue to exist in one form or another.

Sometimes, I wonder, do the flowers also have some goal? What about the goal of animals, trees, birds, etc, after all, they are also part of the same nature. Is there any goal for earth or other millions of planets and stars, which we know are existing and others many more which are beyond our imagination?

What is this goal? Is the real goal is struggle for survival or something more?
