I have come to discover that remaining silent and having to write or act out (i'm becoming very good at charades) what you wish to communicate, involves a much more deliberate thought process than just speaking out. Although, the ability to still be able to spontaneously text message someone is still an ever present danger....
We can be so eager to express our opinions while ignoring everyone else's. Brilliant and salient insights are lost, due to the noise of our own voices. I have been guilty of this many times, and it is to my own detriment.
Two big mistakes you can make in life are having too strong an "opinion", and thinking anyone else wants to hear it.
