It takes literally a lifetime to learn to ride safely!!
I took the MSF course too, great course. I can still hear my instructors voice in my head when I approach certain situations. (she was a pretty blonde and rode a BMW)
Anyway, I learned at my own pace, usually early sunday mornings at daybreak I would ride for 2 hrs. Start/stop accelerate/up shift down shift etc.
My pace, not rushed nobody behind me making me nervous. I loved it. Then I joined a riding club when I was ready. I only do things when I feel comfortable.
Ride your own Ride
Cheers
