I like this approach. Start with trying something small, and if that doesn't work, proceed to the next biggest thing on the list. I imagine over time, you probably will know when you're struggling so much you can skip to step 3 immediately and go out for a walk as you get more in tune with different levels of creative block.

Certainly gives you a different perspective on a problem!

What may seem/be useless for one, may be that very one magic unblocking thing for the other.

Very good point. Probably why I thought most advice was useless because I hadn't really tested what works best for me, although some advice I've read is clearly useless nonsense such as "Remember how lucky you are to be a creative person and quit your moaning". How is that supposed to help?!

That worked very well for me yesterday. I'm currently travelling the world with my wife and our motel in New Zealand has a pool, so I went for a swim for about 30 minutes. I got back into the flow of work again no problem.

Sometimes that works for me, other times it just makes me more frustrated with the problem I'm trying to solve. I wish that would work for me every time!

I started out purely as a designer and quickly built my first ever portfolio site in Flash because I didn't have the time to learn HTML and CSS until I was suddenly made redundant and I had plenty of time to teach myself. I watched all the videos from the Lynda.com course, CSS for Designers by Andy Clarke and Molly E. Holzschlag: http://www.lynda.com/CSS-tutorials/for-designers/216-2.html

I went from thinking I could never learn to understand CSS to being confident. It covers the basics very well, although it's now almost 7 years old, so definitely isn't the best place to learn everything but I still think it's a great place to start, especially if you don't know anything at all. Then you can branch out and learn CSS3.
