It also buys you time to develop your style, values, and pace before you share your work with others. Sharing your work will naturally happen after you have a few pieces that you value. When sharing does begin, the pieces don't have to be finished and they don't have to be revealing or deep. Keep them simple at first. Write every day.
Writers are creatures of habit by necessity.
Those who become very good at writing do it every single day. People who write regularly have decided to prioritize their activities so that writing becomes a prime part of each. While it is necessary to schedule a specific time for your writing, it can also be terrifying to think that you have only so much time to get it down on paper. This pressure can be counterproductive. Go ahead and give yourself the opportunity to write at scheduled times, but also be ready to pull over to the curb at any time of the day or night to get those thoughts down right away.
