Combine what both Junior and TBM said. Get the best passes you can in year 12 to maximise your opportunities but keep following your dream.
I was convinced by my country flying school CFI that there was no future in commercial aviation and chose a different path. The year? 1978.
My CFI ultimately retired as an international long haul check captain with over 27,000 hours. Guess he was wrong about his gloomy forecasts.
Lucky for me I've had a good life away from aviation. I only regret my decision not to keep flying every second day now. It's slowly getting easier.
