There’s one of two ways you can choose to live your life.
The key element of how happy you are will depend on which side of the fence you choose to be on.
It’s in your hands.
On one hand you can have a pessimistic view of existence, on the other hand you can have an optimistic view of existence.
Both pessimism and optimism can serve you fully throughout your lifetime but it will be your decision alone to command your life to become what you view it to be.
