To dig a straight furrow, the plowman needs to keep his eyes on a fixed point ahead of him. That keeps him on a true course. If, however, he happens to look back to see where he has been, his chances of straying are increased. The results are crooked and irregular furrows...Fix your attention on your...goals and never look back on your earlier problems....If our energies are focused not behind us but ahead of us--on eternal life and the joy of salvation--we assuredly will obtain it.
