It is not easy to live and succeed as an atheist. Not due to the lack of purpose. It is that religion makes it easier. There is reward for just believing regardless of doing albeit the effort involved in that doing. There is a God watching over you and taking care of you. There is also the lack of probability. Something definite that is already specified by God is what is going to happen to you. Not everything is possible or probable. There is no chance or risk. It is all predetermined. It is all picked by God. Something in particular is going to happen, not anything might happen. And that is already determined from the start before you were created. Besides, You will end up in heaven anyway, whether or not you will be thrown in hell for a while preceding that. Above that there is a God who would get you out of trouble, and if he doesn’t you would pray until he does. This is absent in the world of the atheists.

Aside from that, virtually all self-help literature is based upon religion. It is not necessarily – if at all – religious preaching, but is leaning on God has something great in store for me, and God has done this to me for my own benefit, and everything is good if we look at it from a different paradigm like God intends to teach us something or has planned something in our favor that will unfold in the future, and we are just supposed to persevere, be patient, and cling to our faith that it will turn out to be something that is for the best.

Generally, there is a deficiency in Self-Help that addresses The quality of life and success without religion. Just like Sam Harris usually says that there is a way to reach spirituality without religion, because almost all guidance in the field of spirituality is accompanied by a huge amount of religious belief.
