It's better to have a small actual advantage than the chance of a greater one.
here is the saying used in a lyric:
Gay Strephon declares I'm the girl in his mind,
If he proves sincere, I'll be constant and kind,
He vows that tomorrow he'll make me his wife,
I'll fondly endeavour to bless him for life,
For all other fwains I care not a rush,
One bird in the hand is worth two in the bush.

Example: "Dan has asked me to go to a party with him. What if my boyfriend finds out? I don't know if I should go." Reply: "Don't go. A bird in the hand is worth two in the bush."

The thing that you already have is a bird in the hand; the things you want but don't have are two (birds) in the bush. You should not risk losing what you have by trying to get something that you don't have. Example: "I've been offered $250 for my stereo. Should I take it, or wait for a better offer?" Reply: "Take the $250. A bird in the hand is worth two in the bush."
