Optimism shouldn’t blind you to the reality.
Pessimism can be helpful when you have to accept the reality even when it is not what you expected and desired.
It is not about hoping that things would get better. It is about seeing the worst yet not being affected by it.
There is no consolation prize in life. There is always a sacrifice.
A healthy realism is productive in the longer run as a feel-good optimism is always followed by a downfall.
