I personally not a religious person. But I do admit that having a religion is a good thing.
1. You have a figure to lean to unconditionally, anytime, anywhere. Even if you're close to your family and had some / many close friend. I think there will be a time for someone that they had a trouble that they wanted to tell others but can't.
2. You know there are superior being, so no matter how great your achievement is, you still have a humble heart. So you won't be too bold of a person. Being too bold is not a good thing for the person him/herself. They feel to superior to learn & hear. It's not good being too all over yoursef.
3. Being religious is good if you know because it teach you to learn about compasion / love, responsible (sin / bad deeds, good deeds), moral and to stay spirited / optimist / hopefull
4. It's also teach you how to manage your time, like you need to spend sometime to come to house of worship as a routine
5. It teach you how to manage your financial, how we saved so we can donate it in the house of worship
