I started with Ford Shorthand (.Com). It took me a few one hour sessions across 3 days to memorize the glyphs. 6 months of practice later, I was writing much faster and more freely--now it didn't matter where I left my notes. I now have a very hard time not automatically switching to this simple shorthand when I'm writing fast. It's just much more efficient.

I also know how to write Gregg at a basic level but Ford was way better for a beginner.
