Never hit the wall and never look back means stubbornness. When you are so stubborn about something that you bump into something as hard as a wall, your head is bruised and bloody, and you can no longer move, then you realize that this path is dead. This is due to personal character. Stubbornness is a derogatory term, which is essentially different from persistence.
On the road of pursuing life, there are always some people who find it difficult to turn back after setting foot on a certain path, even if that path is clearly impassable in the eyes of others. When the results are good, people praise it as "perseverance"; when the results are not good, people praise it as "stubbornness". There are too many side roads that we cannot see clearly before we take them. When we see them clearly, we often cannot re-take them. However, fortunately, we can also recognize the psychological mechanism of others from the experience of "not turning back until they hit the wall", and develop it into indirect experience to save ourselves.
To put it simply, the more you pour into something, the harder it is to let go. For example, you want to change a job, or end a bad relationship, but you don't do it. You continue to be dissatisfied just because you consciously calculated the cost of it. Once you give up, these things will pass. The cost investment will become meaningless, and this kind of loss will definitely make your negative emotions burst.
