Educating yourself each day is a major factor of the 28 day challenge. The more you know, the more you can grow.

Here are some suggestions: Get yourself a Study Bible and go through one of the four Gospels. Read all of the study notes and absorb as much wisdom as you can. Another suggestion is to get a daily devotional and spend some time on the reading of the day. Last but not least, get a book on a topic that you’ve been wanting to study and commit to finishing it within the 28 days.

If you prefer an online devotional Bible Gateway has a bunch.
