just discovered Creativelive courses, which are free and online. https://www.creativelive.com/
I've signed up to a surface pattern course which is on next week and streamed live from the States. Obviously it means 5pm until midnight each day (you can buy them if you don't want to stay up).
This week the tempting offerings include, guerilla film making, heroic public speaking and writing metal music. There's a few strangely titled ones including a course in ugly sweater design (taught by a taxidermist). There' s always stuff on Adobe, craft and design and being better at your business, if you want to play it safe.
