UN-learning and RE-learning how to quilt

I've been making all types of quilts for almost twenty years as well as
having taught quilting classes for about 6-7 years in the mid-90s till
our local fabric store went out of business. I've found that I need to
go back to beginner's books periodically and un-learn or re-learn my
techniques. I *know* how to do it, but I find sometimes I wander off
the path and develop bad habits and/or get sloppy (mostly in my cutting
and safety practices with the rotary cutter). If my basic skills
aren't excellent my more advanced skills will suffer since I don't have
a strong foundation to build on. Also, new and better methods and
tools are being developed every day and I need to keep up with the
advances being made in our craft.

Do you find yourself getting in a rut or complacent and needing to
un-learn bad habits and re-learn correct basic techinques?
