I take a daily devotional to work with my bible with me every day which helps me through the work day and keeps me focused on the Lord. Then when I am off of work, I feel more inclined to continue my reading. Read a chapter or two every day, something manageable that won't leave you burned out, or more, whatever you feel you can manage. While keeping in mind, there are a lot of different books, remember it is one larger book. Or read and reread certain books until you have a good grasp on it then move to another, whatever plan might work for you. There are different reading plans like read the bible in a year, 6 months, 90 days, 30 days etc...
A huge thing that keeps me INTERESTED....is if I find myself not finding the time, I reread something I am familiar with that charges me up. Like Shadrach Meshach and Abednego, or David and Goliath, or the book of Job, Jonah and the fish, read the gospels, read revelation....
Read what interests you. Don't read what interests me, read what interests you. Because that's ultimately how YOU are going to stay in God's Word. Then take that and read other areas of the bible, then pretty soon, you've got a lot that interests you.
