"Humans have four limbs just because you lost two doesn't mean you have to stop moving forward 

Losing every limb? Use your teeth to move yourself 

Not having teeth? Imitate a snake and you will certainly have a higher chance to move than using a teeth 

That's what I've been taught since I was young 

No matter how painful it is, no matter how much damage it cause 

As long you are alive, move forward no matter how rough, and prickly the road is"
