come-on guys, take the good with the bad and YOU decide the course of action. Careful of 'biting' at a reply that you consider negative on the thread, If you bite as easily to criticism when you are a Mil Pilot (or aircrew), you will not last long. Whether you like the comments or not, take note of them and self-filter the BS. Deep down, there is often a point to all replies to topics like these, and emotions will get you nowhere.
By the Way. Good Luck. I initially became a Nav(25 yrs ago I might add) -having failed Pilot selection. I too told them to 'stick it!', but was convinced to change my mind, and was lucky enough afterwards to somehow re-apply once 'in' and became a FJ pilot 6 years later.
My point is:
Never Give UP!!!
