I guess it all depends on what your goals are. A pilot is at Point "A" and wants to be at "B". As we know, there are a myriad of routes to take from Point "A"-- Military: AirForce, Army, Navy, Marines, Coast Guard, NASA, NWS, NOAA , Air Guard --Helicopters, Heavy Jets, Fighters, Props, etc. Civilian: Banner Tow, CFI, CFII, MEI, privately owned a/c, Corporate, Commuter, Freight, Flying the pipeline, Alaska Bush Pilot, Traffic watch, etc. There are numerous subcategories such as "Do I instuct at a flight school or on my own, do I fly for a corporate with props or jets, G2's or Challengers; a commuter with Dash-8's, or Dash-7's, etc.; Should I go Navy or Airforce or Air National Guard, fighters or heavies?"
Not all these options are available to everyone. This could be because of medical reasons, family obligations, financial limitations or geographical limitations, age requirements, or experience requirements, etc. These are factors that you bring to the table. This doesn't even include being rejected by the government or employer, or ,if your goal at point "B" isn't currently available due to military cutbacks, airlines not hiring, or pilots on strike. These factors may be out of your control.
What is your goal? Do you want to fly fighters? Do you want to fly regionals? Do you want to fly for the majors? Figure out YOUR goal and then start YOUR path.
Do I harbor animosity toward someone who got fighters and I got heavies? Am I malevolent toward someone who got hired before me because of there age, family, financial backings or race? Do I hate someone who got the instructor job and I didn't? Will I not fly with someone who's father paid for everything and I had to take out loans? NO! And you know why? Because I don't blame or hate someone for having good fortune. It's futile and it's a waste of time and energy that could be better spent focusing on achieving MY GOAL, not theirs. Stop worrying about everyone else and start focusing on getting to point "B", YOUR way.
