Is it really a choice?

If it is a choice then who does not want to be happy?

Yeah, it is a choice only in a limited way. But before it is a choice, it is a chance.

Do you have a choice when you are born in some remote part of Africa or India where you have no access even to something like clean water?

Was it your choice to have been born in the US or UK?

It becomes a choice only once you have been favoured by chance.
