How do I change myself ,everyone says me that I always talk too much, hence no one respects me but the reason for talking too much is that one, that I always explain each and everything with full details and information what should I do. How do I be attractive

Maybe tone down all that information, and details. People who talk too much, rarely listen, and listening shows interest. People love it when others are interested in them, and what they have to say.

First what do you mean by attractive ? Often that is merely physical appearance, you do that with make up, proper clothes and so on.

If you are explaining everything, stop, only explain if someone asks.

Your attractive just the way you are! Don't change for anybody!

People that talk too much are often insecure. Insecurity is not an attractive trait to most people.

Sit and listen to what people are saying. When you contribute to the conversation try to make it interesting, without going on and on. Show interest in what others have to say instead of dominating the conversation with useless facts and too much info.
