If you are not getting compliance with something you want to occur, quit saying the same thing over and over, getting louder and louder, assuming everyone is stupid, unwilling or defiant.

You’re the problem, not them.

People want to do well in life.  If something makes sense, and they can see the value in doing it, they will.  If they are not complying with what you are asking them to do, then there is something about your request that is not understood or doesn’t appear to have a validity. 

Instead of remaining frustrated, find out what they are objecting to and work it out.  Don’t just keep pushing.  You may not want to hear what they have to say,  but you need to listen.  They may provide an angle that you never took into account. 

The fact that you are genuinely interested in their opinion, will go a long way toward resolving whatever is stopping the forward motion of what you are asking.
