"The secret of success is constancy to purpose." Benjamin Disraeli.
When a dog I owned long ago wanted to go outside, he scratched the door. If no one responded, he hit the door. When we continued to sit doing whatever we humans think it’s so important to do, at the dinner table or desk, or in front of the television, he would then bark. He would look at us hard. Then he'd bark louder. He'd often even come over and scratch my leg. He’d be up in my face in no time, with extremely loud, and very insistent barking. And guess what?
No matter what was going on, regardless of what else might be demanding my attention, the door would get opened and he would get out.
Did Disraeli ever watch dogs like that? I suspect he just saw what universally works, in his own life as well as in the careers of other highly successful people. Constancy to purpose is a version of focused tenacity, a persistence that will not give up or be distracted from its intended aim.
Too many people think that the secret of success is luck. Disraeli was more on target. Constancy of purpose will make its own luck. Remember that today. And watch dogged determination work.
