Only you can answer this, but IMO four months is not enough time to differentiate between the first and second readings. Spend more time reading other books on your list, growing and changing as a person, and maybe in another year or two pick it back up.

My favorite books I re-read about once every two or three years. By now there's no more 'deep thinking' that happens, but they're comfort books for me and re-reading them keeps them fresh in my mind for when I'm asked for a recommendation. Sometimes I do get something different from them if I've had major life changes in the interim, like moving, starting a new job, something tragic, etc.
