One big difference between Glider and Powered Aircraft is the Glide Ratio.
In your Cessna you get about 12:1, maybe less (10:1 )with flaps and Slip.
But in a Glider you have the 40:1 clean option, down to 3:1 with full Air-Brakes, and if you add a side-slip, it is nearer 1:1. So you have a better choice of fields, and your landing run can be measured in feet, and not furlongs.
