is it too late to rush a fraternity?

Let me start off by saying that I'm a 22 year old guy and I'm Junior. As a person who is the first in his family to attend college, I never understood really what a fraternity was all about. When I first came to college, joining a fraternity was something that I had absolutely zero interest in. Now that I have been on campus for a few years, rushing a fraternity is definitely something that I have become interested in. I now see all of the good things that fraternity men do, and how great brotherhood really is. I would love to be a part of something like that. Now, even though I am a 22 year old junior, I have at least two more years left of college to dedicate to Greek life since I have changed my major. I was wondering if I could get some advice on whether rushing a fraternity would be a good thing for me to do, or not? Please don't hold anything back, I appreciate all of your feedback! Thank you!
