to make a sense to our lives.
to make a difference between us and the animals.
to respect ourselves,
to have a self esteem and self confidence.
it's not only higher and quality of life , if is it true so, why the rich people learn and educate. our brains are a great gift of God and we should improve them and feed them by learning and education.
don't look to the study as a part of your life but as a joy of your life.
