Some people say too much; others don't say enough.
A lot of the time, both are motivated by some type of ego protection.
I have an aversion to saying too much. So, it is easier for me to believe it is better to not say something.
As I grow, however, I sense I need to err more on the side of saying too much, rather than not enough (it is likely that err will be involved either way). I suspect I would have more regret over what I didn't say, than what I did say (especially, knowing my tendencies above).
It is true; each time I have done this, it has cost me something. But, at the same time, it is also true that what I have discovered by doing so has, perhaps, been even more valuable than what I have lost.
Someone else once said something about this type of saving / losing proposition about life....
Note to self—it is time for me to say more.
