I find pictures of elegant workspaces inspiring. They really make me wish to clean, clear and reorganise my desk and files.
This is my favourite image, I am sure this space was made for me: it has my computer, the first letter from my name, a book on Chanel, and a faux fur chair cover.
+ clear out you pens etc. regularly so you only have those you need
+ have multiple storage solutions: folders, boxes, files etc. where things need to be placed.
+ reorganise you desk space as a way of refocusing between tasks
+ clear before you leave by aiming to stop work 10 min before you need to exit
+ have items you love on the desk as an incentive to keep a clear space to display them.
+ blank notebook
+ pens / pencils
Other display items can be added to beautify your space and changed regularly. Jars of sweets (peppermints / milk bottles / white jelly bellys) and fresh flowers are my favourites at the moment.
Lastly, ensure you have lots of light (window / overhead light / desk lamp) day and night work, and a pleasant scent (candle / fresh flowers / infusion sticks).
