Try googling "bible reading plans". There's straight through, alternate OT & NT, Genres (different type of Bible literature every day--law, gospel, history, etc), OT & NT at the same time, chronological order of events, order the books were written....You can also find "sampler" plans where you read parts, but not all. Try some out, if you don't like them, try another plan.
I pick one out, print it, then use the printed sheet as a bookmark. Some days I might read more, others less, than is on the plan, and I ignore dates. If I don't understand something, I read it again, maybe in another translation, and then I might check cross-references or study notes or a Bible commentary or handbook. Then, as Martin Luther said, praise God and keep on reading. Some Bible editions have introductions that tell when each book was written, who wrote it, and some historical notes. It helps me some to know the "original audience". I find it helpful to skip around a little sometimes, for variety. I like to read a whole book at a time, but not necessarily in the order they are printed. No matter how many times I've read a passage, I always find something new. But one suggestion--do not start with reading in the Old Testament prophets. Start with Genesis or the gospels.
