英文諺語 A bird in the hand is worth two in the bush
A bird in the hand is worth two in the bush 一鳥在手勝於兩鳥在林
不要太貪心. This expression means that it is better to have an advantage or opportunity that is certain than having one that is worth more but is not so certain.
“A bird in the hand,” is yours, and it’s not going anywhere unless you let it go. But if you leave it and go for “two in the bush,” there is no guarantee you’ll catch them, you might end up with nothing in the end.
In essence, don’t be greedy and stick with what good things you already have, instead of going after something you’ll probably never get.
