Actually life is always a struggle lah........To remain happy, we must be contented with what we have now.
Thats why, when a baby is born, the first thing he does is to start crying loudly......so far....we have not heard of baby laughing at birth.
As soon as he is born, the climb is always uphill.
Thought that when the baby cries at birth, it is because they have to start breathing air as the air replaces the water in their lungs. It can be quite painful. In some countries, they have the baby delivered in water so the baby didn't cry when birth because the baby doesn't experience the situation change. Some even smile thinking they are still in their mum's tummy.
But I do get what you meant...life is hard.
