I believe that the very purpose of our life is to seek happiness. That is clear. Whether one believes in religion or not, whether one believes in this religion or that religion, we all are seeking something better in life. So, I think, the very motion of our life is towards happiness.
Do not worry about not holding high position; worry rather about playing your proper role. Worry not that no one knows of you; seek to be worth knowing.
Do not be afraid of a small beginning. great things come afterwards. Be courageous. Do not try to lead your brethren, but serve them. The brutal mania for leading has sunk many a great ships in the waters of life. Take care especially of that, i.e. be unselfish even unto death, and work.
Drop the idea of becoming someone, because you are already a masterpiece. You cannot be improved. You have only to come to it, to know it, to realize it.
