"Permanence, perseverance and persistence in spite of all obstacles, discouragement, and impossibilities: It is this, that in all things distinguishes the strong soul from the weak." ~ Thomas Carlyle
I say it is Determination, Dedication, Diligence and Discipline that will bring on our "permanence, perseverance and persistence."
And in the memorable words of Forrest Gump, "And that's all I have to say about that."
