I'm in high school too, so obviously I think it's okay to start thinking about rush!
I've grown up listening to my mom talk about her sorority and all the fun she's had, so it's only natural that I'm very interested in greek life. If all goes well, I'll end up going to school veeeeery far away from my hometown, and I hope to join a sorority that will be family away from home. It's a lot of fun to fantasize about your future sorority and sisterhood, and it's never too early to start networking for recommendations

Additionally, having good conversation skills can help you in a lot of other aspects of life. It's a great idea to start working on them now, regardless of whether or not you ultimately end up being a sorority girl. I love reading recruitment stories just because they're entertaining, but they will also help me learn from the rush mistakes of others and to imagine my own happy ending. You can also read some of the topics devoted to rush tips.
In all honesty, the presence of greek life is just another factor that helps me narrow down my college choices.
