Blooze - No pressure! That was my big mistake (although my face paid for it more than I did) when learning. I thought I was using light pressure after using double-edges, especially aggressive ones like the old open combed Gillettes or adjustable Gillettes on 9. Need a super light touch and really really good beard prep. Double edge blades seem to hack through better, so are more forgiving of prep work.
It's taken me a long time to get even half-way decent at stropping, too. That killed sharpness faster than poor shaving technique. I wasn't stropping enough laps, and excessive downward pressure on the handle while in motion.
