I learned not to put all my eggs in one basket.
I learned to do the job and enjoy life outside of aviation.
I learned that your job is only secure as your next medical.
I learned that aviation is about as secure as a keg of dynamite.
I learned not to light the fuse.
I learned to recognise the writing on the wall.
I learned to know when it was time to leave while I had the choice.
I learned......I learned! -)
