A friend recently shared that he tried to read Tozer's The Knowledge of the Holy every year. And since making reading lists that I have no hope of ever completing is a hobby of mine, I've been making my own mental list ever since.
The list is not comprehensive, nor is it (for me, anyway) realistic. I do believe that if a book is worth reading once, it's probably worth reading twice. But I'm probably not going to live long enough to read all the books I want to, which makes re-reading books all the harder to justify.
Which books did I deem worthy of an annual re-read? See the list at Writing and Living.
