So, I've been DE shaving for about 3 months and using a brush and soap for about 6. Here's my assessment:
1) Finally over the last 2 weeks I'm starting to consistantly get DFS-BBS shaves daily with little to no irritation. It feels good to get to this point, and I'm now getting the best shaves of my life. That wasn't true for the first couple months. Don't get discouraged.
2) It takes LOTS of practice to get technique down. This was a big surprise. I thought the learning curve would be shorter.
3) Every minute you spend learning to lather correctly is more than well worth it. Even the most expensive soap is cheap on a per use basis (cheaper than canned goo per use), so don't worry about "wasting" a bit to learn how to lather. You're not really wasting it!
4) Obviously, no pressure really means no pressure.
5) If you're new to DE shaving, don't start with the sharpest, most aggressive blades; work up to them as technique improves.
6) Engrace your ADs. I'm currently suffering from SSAD and RAD even though I have 2 razors en route as well as a passle of soaps which are all due to arrive on my birthday this weekend. I'm now also intrigued by straights. :)
7) Embrace every shave as a learning experience for the first few months; even if you cut yourself to pieces.
