Are the words of thomas paine enough to keep you at valley forge

The words of Thomas Paine in the phamplet American Crisis were enough to keep the revolution going and muster the troops under George Washington's command in 1776. In 1777, when they were suffering heavy losses due to the winter at Valley Forge, it was loyalty to the Patriot cause and to George Washington while training and doing drills that kept the troops busy and allowed for them to leave Valley Forge in 1778 more disciplined and spirited.
