Someone once said that that the way you could tell if someone was crazy by watching them do the same thing over and over and expecting a different result.
If you think spending more money will get you job on top of the bucket loads you have already spent you are a little crazy. There are jet qualified people out there now by the dozen who cant get back in the cockpit. P2F does have limited success for a small amount of people. For over 80% I would say its money wasted.
Please stop spending money hoping it will fix your problems.
