I think you should learn, of course, and some days you must learn a great deal. But you should also have days when you allow what is already in you to swell up inside of you until it touches everything. And you can feel it inside of you. If you never take time out to let that happen, then you accumulate facts, and they begin to rattle around inside of you. You can make noise with them, but never really feel anything with them. It's hollow.
