If you can't find a time and a place in your current environment where you can concentrate and reflect, you will never arrive at any truly creative ideas.
You simply can't spend your days running from activity to activity, from errand to errand, and expect to come up with anything interesting. And even if just by luck you do come up with something creative, you'll need quiet time to figure out how to express it well.
What I'm about to say is perhaps the single most important piece of advice in this entire blog: If you want to be a writer, you must create extensive quiet space in your schedule. Furthermore, you must also create a physical space in your home where you can use that quiet time. Make that place and this time as important as anything else in your life.
This includes protecting your quiet time from self-induced interruptions, especially from internet-based distractions. That means turning off Skype, Facebook, email, chat, online games or anything else that might tempt you into wasting your precious time.
This quiet, uninterrupted time--and the workspace you've created to use that time--are by far your most valuable assets as a writer. Protect them.
