“The greatest part of a writer’s time is spent in reading, in order to write; a man will turn over half a library to make one book.”
So says Samuel Johnson.
The best possible writing lesson can thus be expressed in these steps:
- Read a lot
- Write a lot
- Repeats steps 1-2 ad infinitum.
There is no better tool to write than to read. Any writing advice, any manual on writing fiction (or anything else) will leave you with one central lesson repeated so often as to be a cliche: To be a writer you must be a constant reader.
