1. Pride (Your too good for him):
If you were raised to be a mommy and daddy's little princess, you can end up thinking no one else is good enough for you, according to the article "deadly signs of dating". Pride is an excessive love of self, everyone has it, but not everyone knows how to handle it. Based on my observation, you can lose your friends or love ones on too much pride or worst, both.
2. Greedy
Is known as a rapacious desire or pursuit or wealth, status and power. Greediness may lead to different kinds of sins, like stealing, lying etc. Striving hard and having everything and anything and sharing blessings is far different from having having it all and keeping it all.
3.Insecurity or being Jealous
This characters are very common for most of us. Each and everyone has our own insecurity, in that case we tend to be jealous to other of what they have and we don't but we always do it the wrong way, instead of making it as an inspiration for us to excell or improve, we often label it as "others fault".
4.Unsensitive/unconsiderate
I observe that MOST of the people nowadays, don't have that "respect for others" attitude. They do whatever they want without considering what is the effect for others. Well, maybe it's good to not care for what others may think as long as your happy with what your doing because you'll have your freedom, BUT, use your mind, and be sensitive enough to care of how it may affect them, and how it will ruin their own rights and freedom. BE PERSON, not JUST A PERSON.
5. Lust
Intense sexual desire or appetite is called lust. Some of us, may think that love and lust come together. But lust alone is not a good basis for love. For ex. In a couple, love making are natural and normal, but too much of it and liking a person for it, is obviously not a part of love. But Lust.
6.Sloth
Is considered less serious among the 7 deadly sins. For me, it is more of one's knowledge and control than anything and anyone. (Wikipedia) label it, as a failure to utilize one's talents.
7.Vainglory
This is commonly known as unjustified boasting.
Pope Gregory believed it as a sign of pride.
8.Materialism
For me, too much love for material things is a sin. Although it can make us happy but it can never complete us as a person. It may contain, excessive buying, or too much spending, even if it cost you more from what you have and can have. Shopaholics are considered materialistic person.
