That's advice I'm going to take. Beard prep is important; I've experienced that. But as I got better and better with the DE, it became something that could be easily overcome. Now I need to get serious about it again.
Today's shave was another step forward. Managed to go WTG over my entire face and neck. Ran ATG under my nose and on my chin; then cut myself trying to do the right cheek -- a nice slice but no big deal. That's when I gave up for the day and finished with my Futur. Felt really good for the third shave. Discovered that the angle of attack has to be far more muted than with a safety razor. There's a long way to go and learning will take time. But I feel myself making progress.
The secret to cutting the **** out of your self with a straight is to draw the blade even the slightest bit along its width. Work on to technique so that the blade rests on your skin without much pressure. Then make sure you don't draw the blade. Takes some getting used to especially in the mirror but you get there.
btw:What worked for me was simulating with a pencil. If I felt myself drawing the pencile along the length of the "blade" I figured I had just cut myself.
