Beliefs

People live in the real world, and they have different beliefs as well. Some people become too material and money-orientied instead of having spiritual beliefs. We can't live without material stuffs (stuff - there is no plural for "stuff"..but "things" is probably a better word), but that doesn't (it shouldn't) mean everything; just be a part of life. 

One should also respect others' beliefs no matter whether you (you cant use "you" here because you started the sentence addressing "one") they believe in it or not. Maybe you can't understand what they say or do. Just like some people don't understand you. *(probably better to use the same word ie choose between "can't" or "don't") It's very important to be have mutual understanding between people with different cultures. 

Anyways, one should have beliefs and also respect others'. (Anways, one should have their own beliefs, but should also respect others' beliefs too.)
