This question already has an answer here:
I'm writing a first-person fantasy novel. I can't exactly figure out how to avoid the repetition of "I" when explaining the actions of the character. Any way I have ever seen makes the story seem like it's being entirely told in past-tense, and I believe that would take away from how I want to portray things.
This question is unique because it asks how to maintain the tense, unlike the possible duplicate.
The possible duplicate also doesn't provide an answer in which the present tense is maintained.
