constructive

If you have a constructive idea about how to improve society, you should share it. Something that is constructive brings about improvement and growth.

Constructive is an adjective associated with encouraging development, physical or otherwise. It is the opposite of destructive, which means "tending to destroy." If you are a constructive member of a community, you are a positive force, interested in building up and improving your community. You’ll often hear this word used in the phrase "constructive criticism," which refers to helpful criticism intended to encourage improvement. Negative criticism, in contrast, is just intended to show a person they're wrong.
