sibling similarities

I've always looked up two my two sisters in various ways. I've always been able to call them for advice about anything, and have always admired them for their achievements. Sometimes I even try to live vicariously through them, bragging about their accomplishments as if it entitled me to some sort of special treatment, and it's mostly because I'm just so proud to have them as family. Most of my friends rarely bring up any mention of their siblings in everyday conversation but with me it's a good bet that one of the elder Sheu's will come up. My own admiration for them has helped shaped who I am, but in a peculiar way that doesn't speak so well about myself. Anytime they begin getting interested in something, there's a tendency that I will too. Things that they enjoy doing, I end up enjoy doing as well.

• Despite the wishes of my dad, they both pursued a career in music. Despite the demands of my dad, I'm currently pursuing a career in music.
• They love food, I love food (by love food, meaning, going to extreme lengths for it. Example, they've gone all the way to Vancover just for the dim sum. I've gone all the way to Berkeley for pizza, and all the way to San Diego for carne asada fries.)
• They like cooking, I like attempting to cook.
• They've both lived in New York while they've attended school. Now I want to go to New York for graduate school.
• La Verne has studied abroad for a year in Switzerland, and is mildly fluent in French. I'm considering applying to the Geneva Conservatory which, is in the French speaking part of Switzerland, for graduate school as well.
• They love traveling. Now I have an itch to go immerse myself in new cultures, my first experience of that being last year when I did go to France for a month, and I loved it.
• But on the other hand, I came to Los Angeles first, and then Connie followed me. Ha!

Is it because I'm unoriginal? Am I just afraid of trying new things for myself, rather waiting for people I trust to try it first and to see how they turn out afterward? Maybe I need to find an original hobby on my own or something.
