Congrats !!

That solo is a flight is an all time rush you will always remember, I don't care how long you have been flying.

Now, set your sights on defining a goal for each flight - work on a specific manuever, touch-and-goes and leave some time for just boring holes in the air. When you get good with your trainer, set up the throws for more movement on all the control and practice all your manuevers again. This is the way you progress as a pilot.
