Analysis of Troubles

Troubles are like showers of monsoon,
without which no flower blooms;
Its such a chain, that continues from birth till doom;
No one can tell when they'll arrive,
Just a bit of experience from them is what we can derive;
They say every trouble is followed by happiness, but
every happiness ends with troubles to put us in a mess;
Some cry in vain & some forget it with a sigh,
Knights boldly face them while cowards choose to die.
