NO is such a negative word, right? For me, not really.
Saying YES can instantly make you agreeable, BUT you cannot say yes to everything.
Sometimes, people tend to agree or say yes because they don't want to hurt other people's feelings.
We don't want to let people down so we end up doing things we really don't like.
I am guilty of this, sometimes. I bet, you are guilty too! :)
But you CAN say no.
NO to people who aren't right for you.
NO to things you don't want to do.
Have the courage to be free from doing things you resent.
