The fine line

How many of you think you have,
All the things you are happy or sad about,
Because you deserve it more than others do
Without any shred of doubt?!
There is no logic and purpose,
That this world of ours goes by;
By accident we exist,
And by accident we thrive or die.
You must be thinking by now,
That my mind is dead or ill;
Please give it a thought or two,
And you will understand what I feel.
If you do what you think is right,
And something goes wrong, to your blame,
Do not take it personal,
That is simply the rule of the game.
There is only a fine line,
Between your deeds and chances;
But that said, it's unexcused,
To idly succumb to circumstances.
