Get stuffs out of your mind
Write things down, or use an app to note them down. Free your mind for thinking and creating. Don’t use it for storage. It’s inefficient and stress inducing.
Want to be more creative and productive, and less stressed out? Free the space up there. Get stuffs out. Put your to-do list down on your choice of medium, anaog or digital, and deal with it when you can. Don’t keep any tasks on your mind.
