gratification
A feeling of pleasure when you get or achieve something.
Gratification is the feeling of satisfaction or pleasure you get when you fulfill a desire or achieve something you wanted. When you finish a challenging puzzle, eat your favorite dessert, or finally beat a difficult level in a game, that pleasant feeling is gratification.
The word often appears in the phrase instant gratification, which means wanting satisfaction immediately rather than waiting for it. Choosing to play video games instead of doing homework gives instant gratification: it feels good right now. But finishing your homework first, even though it's harder, leads to gratification later, when you can relax without worry and earn good grades.
Delayed gratification means choosing to wait for a bigger reward instead of taking a smaller one now. If you save your allowance for two months to buy something special instead of spending it on candy each week, you're practicing delayed gratification.
The ability to balance these matters. Sometimes instant gratification is fine: enjoying a cookie after dinner brings simple pleasure. But always choosing the easy, immediate reward over long-term goals makes it harder to accomplish anything meaningful. Learning when to wait and when to enjoy the moment is part of growing up.
