I find my novel having either too many I this.. I that.. and if I do change the sentence structure then it seems I'd be changing it into another sentence that'll come up a lot like " I walk down the stairs quietly" into "Quietly I walk down the stairs". So I am trying to figure out a effective solution. Is there any suggestions, advice, or recommendations anybody has?
A thread was made about this before, but I'll answer your question and try to link you to the thread. I, in 1st person POV, should usually be reserved for when you do actions or dialogue tags or when you hear something. For example. I did my homework. I told my Mom "Good bye." I heard the sound of glass breaking. "What happened," I said. You don't need I for things that you perceived through your senses like the following. I saw an elephant at the zoo, can become, There was an elephant at the zoo. The latter can be like that since the reader knows you are at a zoo and what they experience is through your POV already. Also, it doesn't hurt to look up stories written in 1st person POV from other writers. I'll PM you a short story made by Raymond Carver in 1st person.
