It will do you no good to learn to write from your heart if there is nothing in your heart.

Get a hobby.

Dive deep into something.

The more that is in your heart the more you can pull out of it.

When you nurture passion for a subject you also grow the desire in yourself to learn deeply of other subjects.

Collecting stamps or flying model airplanes or fly fishing or furniture-making doesn’t just increase your knowledge of those subjects. It grows your desire for  the heart-swell that comes from having deep knowledge and interest.
