Enjoy! but don't expect to be sent off by yourself if the weather is dodgy, remember they're not worried about your capability, they just want the glider back in one piece.....
And my advice to you is this: solo is only the start of learning! yes, take off, do a sensible circuit and a nice landing. and then learn to soar, upwind of your airfield, stay up for half an hour, climb to 3,000 feet or more, learn to find the sweet spot under that cloud, learn how to find thermals when low by recognising
trigger point and sources. Remember to carry a data logger, learn to read the maps. Don't rely on GPS. Eventually that first cross country.....flying in strong winds safely (handling the aircraft on the ground takes special care). There is a whole new world out there, learning to use a ridge, to go rock polishing, recognise wave, fly in mountains, o my. We never stop learning in gliding. Solo is only the beginning.
