I saw a post on Facebook about a person who thought a lot but could not express their feelings out loud. But this might be good since we should know when speaking is appropriate .
People can think of many things-both good and bad-but sometimes choose to speak only about the good things. That's not very sincere.
If we say only good things while we think badly, we won't learn to think in a more positive way. But if say everything we think, it creates bad relationships.
We should learn what is good and bad and say only good things; it will craete a good atmosphere. We have to change our mind of thinking to think of good things only.
