I've heard people say that before and it makes little sense to me because some people have a mental illness. And because of that their minds will be in hell no matter how possitive they think. So I don't think it's fare to say that hell is a state of mind and that the level of Heaven or hell you get in the after life depends on your thoughts while alive. It's not fare to say that because of chemical inbalances. I can say 1,000 affirmations per day but if I have a mental illness then it's only going to help so much.
