Don't do it. You are not nearly committed enough.
Flying was the only thing I wanted to do, since knee-high. Yes, on basic training , still not eighteen,I did get homesick. Lying awake at 3am, in a barrack-block, thinking "If I left now, tomorrow morning I would be home, Mum would cook me breakfast, and I wouldn't have to run round the perimeter-track in the fog". But I also wouldn't have been an RAF pilot. Twelve years military, twenty-seven commercial, and never doubted it. I always had a little prayer "Dear Lord, save me from the daily commute, and I'll never complain about doing walk-rounds in the rain at four in the morning"
