I studied an article written by Wang Anshi in high school called "A Trip to Baochan Mountain", which recorded his experience of traveling with his friends. During the tour, he returned halfway with everyone and regretted it; He himself: "regret" and "follow it", and commented that "as long as I fulfill my ambition and fail to achieve it, I will have no regrets." It probably means that as long as you try your best to do something, you won't regret it even if you don't succeed. On the contrary, if you follow others and give up halfway, just like when you travel to the mountains by yourself, you will always regret it.
