Onward and upward is right. Each milestone you reach, you're already looking ahead to the next one. First solo - great. Then there's the remains of the exams, then 3 hours circuits, then nav trips, solo nav, ten hours solo total, check ride. By now you're already thinking about where to hour build for CPL....
Congrats on the solo - it's a great feeling, but keep that momentum going. It's step 1 on a damn big ladder.
