Congratulations Ron
One of the big milestones and the best news is that some of the others- first solo nav, first solo land away- are as good or even better.
I found a point towards the end of my training when it all suddenly became very serious and grown-up as I realised that though I was always going to be learning to fly I'd soon be doing so as a licenced pilot. That was twenty years ago last weekend and it's still the best thing I've ever done.
