Write Daily! – Create a writing routine, the same way you brush your teeth daily, write daily. In order to write about memories, focus on an antique object in the room, or listen to a piece of music from your past, or take a sniff of a perfume you wore years ago. Then allow yourself to write from the heart about what goes through your mind when you do that. Enjoy! Have fun writing!
