If you can remember what it is you're fighting for, holding yourself accountable in your training should not be an issue. What is your reason "WHY"? What is that thing you can hold on to in your mind and your heart that will not only allow you, but MOTIVATE you to stand your ground against the worst? What will make you WANT to stand strong against the storm and embrace every fear otherwise telling you to retreat? If you can find your "WHY", you will without a doubt find the will.
