If I tell you your dress is stained at the back, but you discover it's true, you know this because I told you and you can't see for yourself

That is why you need to mind what people say about you "don't be nonchalant" about what they are saying, just take what they say and get better, people are seeing you from the outside, they have a better view

But don't make the mistake of taking it to heart it causes bitterness
