For me personally, life without religion is many times more enjoyable than life with religion.
I'm no longer worried about the state of my soul with respect to the afterlife, and even more so that I'm not worried about anyone else's soul. I find myself able to accept people as people instead of as "unsaved people" or "nonbelievers". I no longer have to have an agenda behind talking to people, I'm not trying to save anyones soul anymore.
I find the idea that there is no inherent meaning to life very stabilising and motivating, as it gives me the freedom to do what I like with my life without the fear of departing from some celestial being's divine plan.
Things that I previously thought important I find myself dissatisfied with. One striking example is saying grace over dinner. Instead of paying my respects to a god, I would much rather pay my respects to the person who prepared the meal, or give thanks to the person who is paying for it.
I have more respect for life, and human life in particular. Now that I realise that this life is all that we have I treasure mine much more. I'm beginning to understand the value of life and how precious it is.
I have an increased interest in the way the world works, and with the universe at large. Before, I was content with the answer that "God did it" and never bothered to really look past skin-depth for some things.
Those are the first things that come to mind anyway.
