It is good to speak nicely and kind words to ourselves because when you speak negative words to ourselves, from those words affecting us psychologically and even physically it can go a long way to affect your self-esteem, and the way we see ourselves.
some people look down on themselves even before others look down on them and it does not really help them at all.
we need to say positive things to ourselves say kind words and good things to ourselves it helps us with our self improvement.
Saying positive things to ourselves helps us to be so confident that even when you hear negative things about you or the bad things people say about you it will not really affect you as much as it will affect you when you say bad things to yourself, like undermining yourself to a certain extent that does not help us to self improve at all.
