How do I become a less tiring person?

So I have always known that I am a little weird and quirky but i do my very best to be the most loving and passionate friend and person that I can. I am Extremely outgoing and love to be around people. I find that people seem to think that I am an awesome person but that I can't really make any friends. One of my only ones told me that I am just a really overwhelming person sometimes and to maybe try to tone it down a little. I have no idea how to do that, I want to start making some actual friendships (seeing as the longest one ive had is going on 8 months). Thoughts?
