How to treat life, bottom line and stop loss?

Life is a process, with a beginning and an end. The whole process has ups and downs, just like a sinusoidal curve, with peaks and valleys and countless cycles. The bottom line is what you ask of yourself. Tell yourself what you can and can't do. I think the bottom line is what you can't do, but what you can do. The bottom line is like the ceiling. It has an upper limit and a lower limit. Stop loss When an act seriously damages yourself, stop it in time. Minimize losses. Just like life, as long as it doesn't reach the back cover, there is still a chance to rebound.
