Agreed. But happiness is more than just a decision. (Anyone who thinks otherwise has never struggled with chronic severe depression from illness, and/or chemical imbalance. You can't think your way out of that.) If you are so alone you have no family, friends, or co-workers, and you have no education, job, or accomplishments... you won't be happy. Isolated is as alone as you can get. Trust me. It isn't happy, and there's certainly no love.
