Congrats -- I soloed last week too. Exactly 7 days ago actually.

The next day I went out and flew through 3/4 a bottle of fuel. The Nerve-wracking thing gets me, still, but only after I get the plane int he air,a nd for the first 5 mins or so of that flight. Once I am 100% sure everything is trimmed out right and the engine is running strong, I'll start loops and rolls and Split S's and stuff and I forget about worrying about keeping the plane in the air, and just start flying the thing.

It's been windy lately so I've been having fun playing with climbing stalls and such into the wind.

Just remember to have fun, and practice makes perfect.
