The human body certainly cannot go back to the past, but the human mind can travel freely between the past, present and future. However, only the mind can go back to the past, and there is no way to change the past. The same is true for the future. So if there is only an idea but no specific actual action of the body, nothing will change substantially. This is the meaning of the unity of knowledge and action, which is only in the present!
(You must think more, don’t just follow others, especially when speculating in cryptocurrencies, slowly build your own trading model, and practice it in unity of knowledge and action)
