Do not cast your pearls in front of swine

I heard a great saying today.
“do not cast your pearls in front of swine”
This is so true. The context I had heard it is was in reference to people who would not accept Open Source as an alternative to proprietary systems ie you try and convince someone that there is a tool that will do the job and it is free but they insist on spending money on a closed system because free stuff can’t possibly be as good, or maybe thats what they know and they don’t want to change.
Don’t bother with them, let them spend their money and go use your time on someone who deserves and appreciates it. Unfortunately some people are like horses and require their blinkers in order to work otherwise they get spooked.
For those interested in where the saying comes from its the Bible. The original King James says.
“Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you.”
(Matt. 7:6).
