I have a reputation for being quiet but I don't want to known as that anymore what to do??

Stay talkative, I guess.

Plus, I'm known for being shy and quiet too. So at least you're not alone in that sense :)

こんにちは I HAVE THAT REPUTATION TOO!!! ok every 年 at the begininng of the 年 im really quiet but soon like あなた did あなた realize that that can get kinda old sooo what i do is get hyper at lunch lolz its worked for me.. after that people will talk to あなた like crazii:)

Try talking to もっと見る people, I think that can help.

Stand out and be confident... :)

Do a barrel roll.
