I suppose there are some obvious ways of hiding God's Word within our hearts, as did the Psalmist. I would think it has to do with: 

1.  Time:   to do with time-spent (how much, how long, how deep?); when and where and how(?) might also be factored in here. Would reading from a book be better, say than reading on-line (with attending links and distractions)? 

2.  Understanding:  to do with seeking to understand what one is reading (inductive study, comparison, reading whole bits, getting time, order, history right . . .); what does it say? what does it mean? what does it mean for me? - for others? . . .

3.  Meditation:  to do with contemplation, musing, entering the story, personalizing (here Lectio Divina would be helpful)

Lectio Divina (Latin: divine reading) is a traditional Christian practice of reading Scripture, meditation and prayer intended to promote communion with God through the avenue of the Bible. It does not treat Scripture as texts to be studied, but as the Living Word of God through which God addresses one personally.

Traditionally Lectio Divina has four separate steps: read, meditate, pray and contemplate. First a passage of Scripture is read, then its meaning is reflected upon; this is followed by prayer and contemplation (on God's Word and His words to me).
