I am sure that steady effort is the key to accomplishing anything you want in life. The bigger the goal, the more intense the effort required.
It will be hard and painful, but embracing the grind and doing the work at the moment is essential.
By working hard and overwhelming this struggle, you establish personal self-discipline, mettle, resilience, and the fulfillment of your wildest dreams.
When the mind tells you to shut down, focus on the moment, give no thought to the enemy, defeat that thought and press on.
