Saw a recent comment on how texting and calling only lowers your appeal, since there's no way you can match how interesting you are in person. It's the truth, and I agree 100%. But how do you maintain that interest when you're away?

Some background- I'm in an LTR of three years. I have my own business, work out, read and my schedule's usually packed so there's only so much time a month I can spend with her in person.
