In this world, there is no such thing as love without a reason, nor hate without a cause! Likewise, there is no such thing as a pie falling from the sky! To obtain something, one must pay a certain price! This is what people often mean when they say one gains and one loses.
There is no perfect life in this world.
No matter who you are, no matter how much power you hold or how much money you possess, life will always have its share of regrets.
Some people may seem glorious on the surface, living a life free from worries of food and clothing, but in reality, they have many troubles behind the scenes, unknown to others.
The poor have the troubles of the poor, and the rich have the troubles of the rich; the only difference is the way they solve them.
