If everything you do is utilitarian, your very existence becomes purely functional and makes you an empty shell.

What you do should not define who you are. Who you are should define what you do.

When the need to be special is gone, that is when you are unique. Significance of life is in its uniqueness.

How successful you are essentially depends on how well you can use your body and mind.  

You are life, and you are here to live, Experience and serve life. No one has any right to have a mission of their own.
