I have had the opportunity to interact with people on many different levels, from romantic relationships, Christianity, personal, social media and much more.
I am sure that if I told many of my close friends that I used to be a shy introvert, they probably would not believe me. The reality is that this is the truth. And to have to speak publicly was absolutely out of the question. I would even get nervous if I was in a group of people and it was my turn to speak. One day I realized which is one of my favorite quotes, “Only Thing We Have to Fear Is Fear Itself”: FDR’s First Inaugural Address
So I said all that to say this many people don't step out of their comfort zones because of the fear of rejection. My question is how will you even know if you will be rejected if you don't try. When dealing with people I have found that there are very few people, if you approach them with a conversation, that will completely be rude, and ignore you. This is how relationships are built. Some of them may turn into long-lasting and very meaningful relationships, others may be just a passing conversation. Regardless of what type of relationship it turns out to be, you must let go of your fear of rejection. A former close friend of mine said to me once, you've never met a person that you can't strike up a conversation with have you? I had never really given it much thought, but he made a very valid point. This character in me, has caused me to be comfortable speaking in any venue and talking with anyone, regardless of who they are.
So I encourage you to let go of your fear of rejection, if that is what is holding you back, and go out and feel free to talk to everyone that you see, that you might want to have a conversation with. You just never know what may become of that conversation.
