Standing up against opposing forces

Q: I lack the requisite energy to stand up against the opposite forces. Where does my difficulty lie?

In the indolence of the will which does not want to make a sustained effort for a long period. It is like a person who moves slightly half a leg for a second and then wonders why he is not already a hundred miles away at the goal after making such a gigantic effort. You cannot expect a persistent inertia like that to disappear in three days because you made some kind of a beginning of effort to resist it.
