Advice for the weak and strong

Walking up the steps of life will never end in victory,
the winning streak will always result in a shock and you will fall.
The numbness of your childhood days will come back 
and the hate of your adult life will arrive to hunt you.
Real monsters live on earth is what you said,
they are strong outside but inside they are dead.
Please listen to these words and you will never go wrong.
If you devour the weakness of others, you will never be strong.
