I work with a computer, but, I see the power of drawing in my notebook after reading the biography Leonardo Da Vinci, he use this tool often to save your thinks, plan, and observable the world details.

We that work with a digital world all the time want for apps that resolve something, but the power of drawing is incredible because it is just you and your mind, as you can send your thinking directly for the world visual, believe in me, it is powerful.

I have bee using this to plan new apps or to save my ideas for the future, and I like to see ideas that I save in the past, believe at it, would you like to see how your mind can be powerful.

Try this, buy a notebook and a pen, and start drawing your things, after some time, come back to see what you note.
