The true measure of a career is to be able to be content, even proud, that you succeeded through your own endeavors without leaving a trail of casualties in your wake.
Man falls from the pursuit of the ideal of plan living and high thinking the moment he wants to multiply his daily wants. Man's happiness really lies in contentment.
It is in virtue of his own desires and curiosities that any man continues to exist with even patience, that he is charmed by the look of things and people, and that he wakens every morning with a renewed appetite for work and pleasure. Desire and curiosity are the two eyes through which he sees the world in the most enchanted colours...and the man may squander his estate and come to beggary, but if he keeps these two amulets he is still rich in the possibilities of pleasure.
Love, compassion and concern for others are real sources of happiness. If you have these in abundance, you will not be disturbed even by the most uncomfortable circumstances. If you nurse hatred, however, you will not be happy even in the lap of luxury. Thus, if we really want happiness, we must widen the sphere of love. This is both religious thinking and basic common sense.
Keep working hard and you can get anything that you want. If God gave you the talent, you should go for it. But don't think it's going to be easy. It's hard!
