Avoiding Unncessary Grief

I was intrigued by a speaker in church this morning who used the term "unnecesary grief."  We tend to think of grief as bad stuff imposed on us against our will.  And, indeed, much grief we must endure does get dumped on our heads unceremoniously, without warning, and without invitation.  But the speaker's point was that we could avoid a lot of grief if we paid more attention, avoided circumstances that lead to grief, thought twice before we exhibited bad behavior, planned for the future, and made wiser decisions.  So there you are.
