I have always been a big fan of lists and schedules for organising my freelance design work. Whenever I get a new design job in, I type it/or write it on to my job list and plan out the rest of my week. I recently found a piece of free online software that is really easy to use called Teux Deux which lets you plan out your week by listing all your design jobs day by day. You can then move them around as necessary, add to them and delete them. It’s a simple idea but very effective.
I have made a screen cast (be gentle with me it’s my first) below to show you its simplicity.
