1 year reflection - is it time to slow down ?

I do not ride that fast, but definitely much faster than a year ago when I first got my bike. Stacked it once (rider's error) and completely lost confidence and rode very slowly since. Well things gradually changed and today had a quick ride to the spurs and walhalla and I am taking corners at 140-160k. More than once my boots scrape the road. It is thrilling and I no longer feel the fun at lesser speeds
So what are your experiences? How do you guys differentiate skill from pure luck ? I mean I actually now believe it is ok to step on gravel on the road. Where do you draw the line and stop increasing the pace ?
