You can only become truly accomplished at something you love. Don't make money your goal. Instead, pursue the things you love doing, and then do them so well that people can't take their eyes off you.
The only way to avoid being miserable is not to have enough leisure to wonder whether you are happy or not.
Never put off till tomorrow what you can do the day after tomorrow.
