It is a great day, but that is a matter of committment to an internal princible, that is, to use one's will to see it as a "great day", but not in such a way as to filter out even an iota of it. With every breath and movement of a finger tip I thank G-d for the opportunity to do good in this world. It is a good to try and see a thing as a good, or at least to ask why. It is not a world of superficial good, and it is also full of pain and troubles. The good must be sought after, intellectually and with the spirit, morevover one shpuls act for the good a person can do, which takes learning and contemplation. Take the time to have second thoughts rather than rash actions.

FYI - people that don't believe in God can be offended by your saying "God bless"

Even if god existed, I wouldn't want the blessings of wrathful god guilty of so many crimes against humanity
