"The inner satisfaction and peace of mind that come from knowing I did the best I was capable of doing."
It has nothing to do with the number of games you win, the number of contacts in your phone or how much money you have. Those as all results of being a successful person.
If one’s life is simple, contentment has to come. Simplicity is extremely important for happiness. Having few desires, feeling satisfied with what you have, is very vital: satisfaction with just enough food, clothing, and shelter to protect yourself from the elements.

Our lives . . . are but a little while, so let them run as sweetly as you can, and give no thought to grief from day to day. For time is not concerned to keep our hopes, but hurries on its business, and is gone.
Philippians 2:3 (New International Version) 3Do nothing out of selfish ambition or vain conceit, but in humility consider others better than yourselves. 4Each of you should look not only to your own interests, but also to the interests of others.
