If you’ve been training for a while and your CFI still hasn’t asked you to pull to the side of the ramp so he can endorse your logbook for that first solo, it’s natural to feel anxious and frustrated. Maybe you've logged 15 or 20 hours, and your friend already soloed. And that naturally has you thinking, "Why not me?"
Remember this: soloing is not a race. Every student learns at a different pace, and your instructor’s job is to make sure you're not just technically qualified to solo, but truly ready.
