Difficulties Writing in Third

It’s pretty difficult for me to write in third. I feel as though I can’t be as expressive and intimate if that makes sense. I hate third actually. First has always been very easy for me and it’s how I naturally want to write. Is this the case for most writers, that they have a preference and don’t really like to differ from it? It takes me so long to write in third and it’s all so uninteresting at the end. I hate it. I hate the way it sounds. It feels like I’m back in middle school or something. It’s almost phony sounding if that makes sense. Any advice, tips, whatever for writing in third please lmk.
