You can identify a fool just by the way he walks down the street!
When the horse is stolen, is too late to lock the barn.
Ecclesiastes 10  vs 3, 11

Don't eavesdrop!   You may hear your servant cursing you!   For you know how often you yourself curse others!
He who loves money shall never have enough.  The foolishness of thinking that wealth brings happiness!   The more you have,  the more you spend.

Savings are put into risky investments that turn sour,  and soon there is nothing left to pass on to one's son.
The man who speculates is soon back to where he began---with nothing.
All the rest of his life he is under a cloud---gloomy, discourage, frustrated,  and angry.
cp 5/ 13, 14,15

Whatever is, has been long ago;  and whatever is going to be has been before;  God brings to pass again what was in the distant past and disappeared.
cp 3  vs 15
