Meditating is good, I agree. I would also suggest immersing yourself in the elements in the natural world, - for example, gardening for earth, walking in the pouring rain for water, and so on. There are many ways, of course. Use your creative energy. Meditating with no organic experience is going to leave you with no meditation material.
Additionally, I personally like to keep things balanced. If you really must focus on just one element, why not focus on your weakest one? A chain is as strong as it's weakest link :)
