The discovery of a new dish does more for human happiness than the discovery of a new star.
What if this weren't a hypothetical question?
Whatever you fear most has no power - it is your fear that has the power.
Those who cannot remember the past are condemned to repeat it.
Glory is fleeting, but obscurity is forever.
Try to put your happiness before anyone else's, because you may never have done so in your entire life, if you really think about it, if you are really honest with yourself.
It is not enough to aim; you must hit.
