Religion. Now there's an easy subject.

Not really, but let’s get into it. That is to say very lightly. Continuing on the theme of philosophy, history, religion, and poetry to be a better writer, this subject like the others should be familiar to you as the writer.

It is a major part of society around the world, so if you are going to write a story that encompasses a certain religion, do some research. Learn about their beliefs, traditions, scripture, and some of the symbols they may pray to.

In my book, Look in the Mirror, my character, Ruth Murphy, is a devout Catholic. She has a strong faith, good morals, and compassion for other people. Her husband, on the other hand, Johnny, lacks all of those virtues. By being familiar with the Catholic religion I was able to reference scripture and beliefs she held dearly in order to contrast that with her husband during some of their personal discussions (and his challenges to her faith.) Having a certain knowledge, weather it is Catholic, Protestant, Methodist, or Jewish, will certainly bring credibility to your writing.

Learn something new everyday, it will strengthen your mind and your soul and make you a better writer.
