There have been a lot of (what I thought were) very difficult parts that I was able to work out over time. But practicing is not strictly about starting slow and speeding up. It's about starting slow, and staying slow until you can speed up. Otherwise, practicing becomes a series of exercises that start slow, then fall apart as the speed is prematurely increased. The learning process is severely hampered if not handled with a 'slow & steady' approach.
quite possibly the best advice i've ever read here and exactly timed and worded to my needs at the moment. thanks man.
