Very well said. Thank you.

The only part I didn't get was the end of the second text: > It would be a life without purpose.

I understand, that this might not seem to be a fulfilling life to you. Though, these people can still have a purpose. It doesn't have to be happiness. As an example, take the nurse or doctor who works unbearable hours in an emergency room, or the soldier who sacrifices his life for others. Some of these people might never be happy, but I would suggest, that their life has a purpose.
