There are some cases when, if you don’t know what to say the best thing to say is nothing at all. But that doesn’t apply to every situation.
In fact, in some scenarios saying nothing is one of the worst things that you can do.
Sometimes we hold off from speaking up because we think that less than perfect is not good enough. However, the perfect composition of words shouldn’t always be the aim.
At times it’s better to speak up in the moment, to perhaps let someone know that you care instead of staying quiet. The alternative is to wait until what you have to say is closer to perfect but by then it will be too late.
