Our culture and our socialization tell us women how to act and think. We are supposed to be women/wives/mothers first and writers second.
Because of this, you need to be clear about WHY you want to write so that you can give yourself permission to write. And just to be clear, some of us have a harder time giving ourselves permission than others do. So,
1. Know what your goal is: it might be to start writing, to write more, to write more creatively, to write a novel, to finish writing projects, to sell your work. Be clear with yourself what your writing goal is.
2. To accomplish your goal, go deep: those who study brain science suggest that you need to answer this question, “what is the intrinsic social, moral or personal reason I have for wanting to achieve my goal?”
Knowing what your goal is and why you want to accomplish that goal keeps the motivation part of your brain activated. The clearer you are about your big WHY (the personal reason you want to write), the more important the goal will feel to you, and the more your brain will be motivated to turn that goal into reality.
When you know your big WHY you will have the motivation to take the necessary steps to find/make/clear time and space for your writing.
