All of the above ^
Seriously though. You want to beware of the shopping list mode. Or maybe its the todo list mode or more exactly the as you do list.
This is where you need to concentrate on less. Go into a scene with the notion of relating those things important to the story and then cut to the next. Following your character around everywhere is not only creepy stalker like stuff, but rather tiresome after a while.
It gets compounded by the overarching I.
The paragraph filled with sentences that all begin with I, seriously two sentences beginning with I in the same paragraph can stand out.
The page or pages that have paragraphs that all start with I.
And just I in general. That can get peppered throughout the narrative.
As to not revealing too much--that can be a balancing act. Withholding vital information has to have a right feel to it or it can become just as tiring as following your characters every move.
Really though writing first person can seem restrictive and also give the impression that the writer has chosen the easy or the popular path. The truth is that it's no different from writing in close third and little different from other POV that draw close to the character.
I like to use something like this next example as a way to show how taking other people's advice can become confusing.
The Danger of Overuse of 1ST Person Narrative in Literary Fiction | Editor's Opinions Blog
In this instance there is a deliberate attempt to do poor first person writing and then it's followed by two examples in other points of view and the argument is that it shows how restrictive first person can be.
However if you read all three examples it becomes obvious that much of what is written in the two better written examples could easily be used to improve the first example, which only goes to show that rather than restrictive it is mostly the same as any other writing.
You need to work at it and develop it in the same show not tell--use all the senses--avoid overuse of adverbs--avoid passivity--Avoid filter words and on and on....
Sure there is a limit to knowing what the character knows and what they can see, feel, taste,smell and hear; and a limit to how or if you can relay anything outside of that. And you have to respect that.
You don't have to let it make your writing become poor or less.
