Write things down. Take notes.
Some people don’t shy away from highlighting passages in their Bibles, using sticky notes or writing on the margins of their Bibles (as medieval monks actually did with manuscripts). All these are surely good habits, as long as one is actually getting something out of them. However, most people recommend not only highlighting or underlining but actually copying the passages we find more interesting, troubling, or inspiring in a separate notebook: writing and thinking are like processes.+
