Life does not believe in tears, and competition does not sympathize with the weak. How to understand?

This is a very rational and even cold-blooded statement. If someone can really do this, then he is not simple, but the material for doing great things. But you should also know that the sharper the sword, the more people will guard against it. So, good or bad is just a backhand. It's okay to stick to yourself and treat it rationally on the problems you can handle, but if the problems involve others, it's too heartless to handle them. 59660.68668686666
