My lady has a saying; "don't look for problems, look for solutions".
There is no success without failure, you must fail in order to learn how to succeed. You must take responsibility for your life and stop hiding from your potential in the bushes of excuses. Attitude is altitude..... All this stuff is very cliche and has been regurgitated by many of these motivational speakers, but the reality is; its true what they are saying.
If one person can get through the exams, get their licence and get a job then that means you can too; that person proved that it was humanly possible. Therefore, self analyse and find out what it is thats holding you back. Short of being medically unfit, anyone can get a job as a pilot if they have enough determination and desire for it.
