“If you don't write when you don't have time for it, you won't write when you do have time for it.”
“Writing is not a matter of time, but a matter or of space. If you don't keep space in your head for writing, you won't write even if you have the time.”
“I don't think you have time to waste not writing because you are afraid you won't be good at it.”
“If you don't have time to read, you don't have the time (or the tools) to write. Simple as that.”
“If you don't have the time to read, you don't have the tools to write.”
“Can I be blunt on this subject? If you don't have time to read, you don't have the time (or the tools) to write. Simple as that.”
