Will power is the power to subdue laziness and procrastination. It's the power to command or reject unneeded or injurious impulses. It's the power to arrive to a decision and follow it with doggedness till its successful achievement.

It's the inner might that overcomes the desire to indulge in unneeded and worthless habits, and the inner strength that overpowers inner emotional and mental opposition for taking action. It's among the fundaments of success, both spiritual and material.
