Hi Lee!!!
Very well done. I remember the feeling well. I went solo about 8 hours ago (8 flying hours) and it was, like you, the best day of my life so far. You'll land after the next solo flight with the same telltale grin - I actually found my subsequent solo flying more exciting and enjoyable than my first solo - probably due to a little more confidence and spending a good 40 or 50 minutes at a time by myself.
I dunno if your syllabus is the same as mine, but I assume it will be similar. I did 3 hours of solo circuit flying (great fun but a pricey business!) and then did PFL's and precautionary landings before getting to where I am now, which is just starting navigation. I think those 3 hours collectively are the best 3 hours I've spent doing anything
No dirty replies please LOL.
