If you're beginning to read the Bible, it might be a good idea to read the narratives first, because you can get a great deal of material into your mind because the story thread holds it all together in your head as you go.
That'll take you a while!
As you go along, follow up some marginal references by the side of words or phrases that interest you, and in that way you'll begin to broaden your acquaintance with the other parts of the Bible.
Stay away from the more difficult parts while you are beginning - like the Epistles, Leviticus, Job, Revelation. Come to them later on, and as you use the marginal references. When they lead you to a particular piece, pause there and read round that bit, to see why they sent you there.
Remember that in the times of the NT, they didn't have the whole Bible as we do, so they had to pay very concentrated attention to the bits they did have.
I think that is an excellent plan - sticking to one bit till you've squeezed all the juice out of it that you personally can get.
I am personally doing that most of the time, and benefiting enormously from doing so. It is truly astonishing what 10 or 15 verses can hold.
Also. and I think this is the most important piece of advice I can give you:
ASSUME THAT YOU DON'T KNOW ANYTHING ABOUT THE PASSAGE YOU'RE GOING TO READ.
Come to it with your eyes wide open, your brain and imagination in top gear, and don't let anybody tell you anything about it until you've worked it and yourself to a frazzle.
Only when you can't POSSIBLY answer your own questions,
only then do you go elsewhere, like to the commentaries.
Until then, avoid them like the plague.
When you do go to them, you'll find an interesting thing happens. If you've asked an intelligent question, you won't get an answer.
You'll get a whole load of blah, because they've either never thought of the question, or if they have, they probably don't have an answer, and so avoid it like the plague! It wouldn't do their reputations any good if they went round saying I dunno, I dunno!
So go to it with a will. Have fun reading it. It's a very serious Book, but if you were a father writing some instructions to his son, you wouldn't write in gobbledygook, now would you? You'd write it so your son would enjoy and understand what you wrote.
That's what God did, and I hope you benefit from His writings.
