How hard is it to get into a frat.

[The Laminater]

I am a freshman and Rush starts in a couple of weeks. Im a little worried because I am not the type that is 100% outgoing. Im not a weird shy kid who doesnt say anything and once I get to know people I am actually really talkative, but I am just a tad bit reserved when it comes to meeting new people. Is this going to have a major impact on my chances? Is it hard to get into a frat or do most people get in(what % of people get in)? Thanks.
