Many people have grand ideas that never take tangible form. Their desires are disconnected from their actions, and their professed goals are never pursued.
You can avoid this trap by walking the talk. Don't wait for someone to give you permission to write by making an offer on your unfinished (or unstarted) novel. Give YOURSELF permission by writing daily, if you can, or as frequently as your schedule will allow. If you're not sure what to write about at first, describe the struggle to come up with good ideas.
Writing doesn't require elaborate rituals, perfectly organized workstations and large blocks of free time. All you need is a few spare minutes and a writing instrument or electronic device.
The best way to learn how to write is to just write. Let the work itself be your guide and your teacher.
