Destiny Doubts

If in the stars we are destined in life,
Which means our fate is already sealed,
Do you think you can really be happy,
If all your life's events were then revealed?
Good events more than welcome they would be,
But all those other situations bad,
The ones that you would now constantly see,
These would truly, cruelly make you sad;
Since our destinies we cannot turn,
Then it's better that we don't want to know,
All the things that are fated to happen,
So knowledge will not deal a deadly blow.
