Using the gym analogy, you can work out hard but should take a break for a couple of days per week. I'm ready to take my playing to the next level.Yes of course take a break so you can recover the muscles . It's like going to a gym you can over exert yourself and injure your back or neck so chill out
I'll try to keep that video in mind. A teacher is not an option where I live as the nearest one would be a two hour drive round trip, even then, there would not be many teachers to pick from.
