Me? A tutor?

I have never been in a position as an “official” tutor so I am a bit anxious. Or maybe very anxious. I think my biggest worry is that I won’t know what to say or I’ll make a stupid mistake; it would be embarrassing to mix up grammar or misspell something. My biggest worry is that I’ll seem incompetent. I also have a tendency to ramble on so I’m going to have to watch myself so that it doesn’t turn into a lecture. My intentions are usually good, but on a few cases I have come across as ignorant. Not to mention I subconsciously fidget and I get distracted rather easily. Any issues that I think could arise have been briefly or extensively discussed. The various tutoring tips I found make me feel as if I am going to have to watch myself constantly.

I think it’s mostly pressure that I put on myself. I don’t want to just be some tutor in the ETC. I want to be a tutor students would be willing to work with again.
