As you grow up, always tell the truth, do no harm to others, and don't think you are the most important being on earth. Rich or poor, you then can look anyone in the eye and say, 'I'm probably no better than you, but I'm certainly your equal.
The seeker after truth should be humbler than the dust. The world crushes the dust under its feet, but the seeker after truth should so humble himself that even the dust could crush him. Only then, and not till then, will he have a glimpse of truth.
Stay hungry, stay young, stay foolish, stay curious, and above all, stay humble because just when you think you got all the answers, is the moment when some bitter twist of fate in the universe will remind you that you very much don't.
