Well...I done such things for the past years of my life. Everytime I moved, I would get rid of majority of the things I really don't need, sell some of my belongings, and give away furniture and etc. It got to the point where the only thing that matters in my life is my laptop, my family, and my mind. Everything else is just a temporary bonus. I always looked at material like something that is temporary, but sometimes I have a connection to it. Especially my own record collection. Yet, once I realize that these items were weighing me down in the process of my growth, it became apparent that I needed to reevaluate my stance in life.
If you really want to understand the purpose of minimalism, I suggest reading this book:
It's a really thought provoking book and help me in the process of my constant moving. Once you realize that these personal belongings are just mere objects, you will see that you are on the perfect path of peace of mind. Babysteps though, but I would look at the stuff that you have and do a ranking system to narrow down the one thing you could careless about. Get rid of it and see how you do in the process.
