set one's heart on

"Mother, it must always be the last chance—the only chance, when one has set one's heart on it."

Two beautiful eyes looking upon you and seeming to say: 'March upon the enemy!' are enough to set one's heart on fire!

To be morally good is to know the good, to set one's heart on the true object of affection; and to be theoretically sound is to understand perfection.

It is not wise to set one’s heart on what one is not sure of getting—or on things that perish with the using—which is emphatically true of jackets.

I had a glimmering of fear of what might follow; of anxiety as to the remedy which this new age might offer for the missing of something one might set one’s heart on.
