Hello and welcome, Celia. The one-thing-at-a-time approach will be just fine. Amber123 recently did the same thing.
The answer to this specific question is rooted in human evolution. At every stage in our development as a species there has been fierce competition for the resources necessary to survive. The survivors all the way along have been not just the strongest or the smartest, but those with the greatest will to live.
We didn't always have religion to drive us, you know. Before our ancestors even had the intelligence to conceive of gods or ponder the meaning of life, if they lacked a strong will to survive they would not have survived and we wouldn't be here. Those who were content not to survive or procreate were quickly scooped out of the gene pool by the dangers of the harsh ancient world. The survivors passed down their determination to us, as instinct.
On a personal intellectual level, I'm an atheist and I want to survive because I don't think I have any other life but this. There is a great deal of joy to be had, and to spread, and I want to make the most of it before I die.

A few reasons.
- I get free on-the-job training in written debate, research and effective writing in general, with rapid feedback if I do badly.
- I'm relatively new to atheism, and I'm crash-testing it. I'm actively seeking the best arguments against it to see whether I've missed something obvious. Nothing so far.
- Many religious folks paint a really horrid picture of atheism and atheists themselves. That reflects badly on me and any of my friends and family who are atheists. I want anyone who's genuinely curious about atheism to be able to ask an atheist about it directly, and set the record straight.
- You call this conforming to morals and customs? I spend half the time here explaining to people why I don't conform to their doctrines.
