You are right! You can spend a lot of time just finding where you are supposed to read for each day. We have found that it is useful to keep three bookmarks in your Bible. One for where you are reading in the Old Testament, one for where you are reading in the Psalms (which are part of the Old Testament), and one for where you are reading in the New Testament. For e-readers, using the bookmark feature of your e-reader works well.
