You've likely heard the expression, "show, don't tell" when it comes to how to create a story and characters that readers will love. Unique traits, mannerisms, and characteristics play a large role in the process of showing who a character is and giving your reader clues about the character's personality without breaking the narration with writing that "tells" too much. So how do you use traits, mannerisms, and characteristics effectively? A lot of it has to do with simple observation.
The next time you are in a public place and can watch people without being noticed, try to find some traits, mannerisms, and characteristics that set them apart from each other. For example, if you see a couple talking and their arms are around each other lovingly, that immediately tells you about their relationship (that it's close). Alternately, if you see a couple and one has his/her arms crossed and won't make eye contact, that is a show of discomfort in the relationship. You can read all of these things simply by watching someone.
In the same sense, if you want to create a character who has social anxiety, instead of telling your readers about the issue, show them instead. Have your character stand in a corner at a party and look uncomfortable. Have him/her imbibing alcohol at a social event to try to feel more relaxed and comfortable around so many people. There are so many traits, mannerisms, and characteristics you can use to relay intimate details about your character without telling your reader more than you should.
With that in mind, here is a list of over 100 character traits and quirks to help you build characterization in your novel. Need more inspiration for your character?
