Replying to Got my gear, getting lessons, NOW WHAT.

This weekend will be my second time on the slopes. I have another lesson booked at a local hill with what they call 50 percent "family friendly" slopes. I assume this is geared for noobs like me.

How does one gauge readiness for advancing hills? Right now I am building comfort and confidence on skis, but how do I know when I'm ready to go from beginner slopes to intermediate slopes and so on. I assume ones red slope could be another's green so how do I factor that in?

I'm asking because I am cautious about my current abilities and on packed hills don't want to hurt anyone and vice versa.
