I never really had a problem with the lower edge of the flight envelope. I think it was because I used to fly model airplanes. You get accustomed to the edge with no instruments and no accurate indication of attitude. You can push the envelope with infinitely less risk. Engine out landings are a common occurrence. So I had a good idea of what was going on.
I did snap a wing spar on a model, and as a result I was scared of pulling g's and felt uncomfortable with the yellow arc of the airspeed indicator. Only exposure and practice got me over that. My instructor demonstrated 2 g's on a 60 degree bank to prove the wings wouldn't fold up. Steep turns got much easier after that.
