Dopa-writing helps you break the habit of endlessly opening social media, short videos, and games. Pause, write out your thoughts and feelings, and make room for a clearer mind. You don't have to give up your phone all at once. Start by putting the noise in your head into words. Stress, worry, frustration, unfinished thoughts. Write them as they are, for yourself rather than an audience. If you don't want to keep them, let them go without saving. Getting that noise out of your head can give you room to think. A clearer mind makes space for new ideas. When inspiration strikes while you write, capture it immediately with Flash Ideas. Dopa-writing is about more than simply restricting your phone. Turn a device you reach for without thinking into a tool for understanding yourself, thinking deeply, and finding inspiration. Build a new relationship with your phone, one writing session at a time.
