Decide what to do And what not to do

This World is a double edged knife 
And we have only one life 
Enjoy it, Live it well 
In good company do dwell 
Always do good deeds 
Sow in yourself character's seeds 
Cultivate mind with manure of thought 
For ages, the experiences brought 
Feed your life with good deeds 
So that there is no place for weeds 
To harm, that oft leads 
The decay of character's seeds 
The one who wants to succeed 
He must always heed 
And must seek 
The good qualities 
And not the quantities 
A wise man can only pleads 
But you have to pay heed 
What are you needs? 
Then decide what to do 
And what not to do
