There is no one to follow, and the next sentence can be "only firm belief as a companion." Emphasize that in the face of difficulties and challenges, even without the support and dependence of others, as long as we have firm beliefs, we can persist in overcoming difficulties. You will feel lonely and helpless when there is no one behind you. At this time, we need to rely on our inner strength and belief to support our progress. A firm belief can give us courage and perseverance, and keep a positive attitude and strong will in the face of difficulties. It is an inner beacon that guides us to success and achievement.
