You need more time, in every sense.
More time between you and the failure and more total time and more jet time.
Walk before you can run grasshopper.
Your initial introduction into a jet didn’t go without a hitch, there’s a reason why that happened.
You’re also very young. Now age doesn’t guarantee maturity but being that young won’t help.
Sit back, relax and enjoy your job.
You probably have no idea how lucky you already are flying a jet at that age with that little total time.
