Pls help fast by today ;-;

In this french correct ? i dont know if the person i am talking to is a female or male im assuming that wouldn't affect it but i kind of forget . i know all adjectives agree with the nouns that they modify. métier is masculine so i use the adjective bon and bon is masculine so i use un? is that how it works je pense un bon métier pour toi est un artiste ou un architecte. i think a good job for you is an artist or an architect

Can someone translate this to french? “my mother swims from time to time. my brother always sings. my grandma rarely dances.”
