Beating a Dead horse is a waste of time and energy.
I understand it is very hard not to at times. Especially when we believe in something so much.
"if only they could see what I see"
"if only they could feel the way I feel"
These thoughts tend to overcome us, so much that we lose sight of the other opportunities that are around us.
So instead of beating that dead horse, find the horse that is strong enough for the ride.
