I will be ambitious with my job and not with my career. Thatโ€™s a very big difference, because if Iโ€™m ambitious with my career, everything I do now is just stepping-stones leading to something โ€” a goal I might never reach, and so everything will be disappointing. But if I make everything important, then eventually it will become a career. Big or small, we donโ€™t know. But at least everything was important.
