If I fall into a rut with reading the cards, I experiment with spreads that I find in books or here on the forum and use them for practice, whether or not I really need to consult the cards. As for trying new things, I have always enjoyed using the tarot for purposes other than reading. I like to simply sift through the cards, admire the artwork, or play a game of solitaire with them. Sometimes I will choose a card to gaze at during meditation. In ritual, I often use the tarot aces to mark the four directions of my circle and choose additional cards as the focus of the ritual. I also like to use the cards as a way to help interpret my dreams. If I don't want to use the cards at all but want to connect with them, I indulge in a tarot project that involves trimming, edging, glittering, etc. Not for everyone, I know.
...And sometimes, unfortunately, I simply hit a time of stagnation in the tarot cycle. My passion for tarot waxes and wanes. Since I don't depend on it for professional or financial reasons, I am okay with putting the cards aside for awhile until the passion comes 'round again on the upswing.
