How do I stop giving information to someone while taking?

I'm having the habit of giving information or telling about my personal things a lot even to random person or to somewhat known person (not closed ones) So how do I stop telling about myself or my life plans or stop sharing my past experiences? During talking I can't stop, I'm an extrovert, so all I think is to build the conversation. But after the convo, always I'm feeling bad and regret for saying those.
