About seven years ago, I was newly divorced for the second time, broke, indebted, depressed, bad at my job and probably about to be unemployed (my entire division was winding down legacy projects and would be laid off within months). Then, my ex-wife called me to let me know she had seen a job listing that I might be interested in.
My ex, who really had no reason to like me, let alone do me a favor, and who had only seen this listing because she hadn't bothered to turn off her email notifications after getting the job she wanted and moving out of state to get away from me, had found what was (at the time) my dream job - overseas, away from everything, making shit-tons of money and totally immersed in the moment at all times. It was the perfect way to push the reset button on my disastrous life.
I rented out my house, found someone to take care of my dog, dove in headfirst, and had one of the best years of my life. Made well into six figures, paid off cars and cards, and piled up enough to take time off with loved ones and check off a whole lot of bucket-list items. It took me another year after getting home to fully stabilize, and my savings were again fairly low, but at least I had worked all the ugly shit out of my system, and my resume' was looking much better. I've been in the same job for five years since then, stashed 250K, and figured out a whole lot of stuff about life and investing. I shudder to think where I'd be if I hadn't gotten that call.
To that, I could add some of the common advantages above. I had some domestic instability growing up, but I always had at least one parent expressing genuine love and concern, encouraging high academic performance and extracurriculars, and pushing me to go to a good college and apply for scholarships. I got my education almost for free, aside from a few hours of work for incidentals, and came out with minimal debt. Due to my grandfather's influence, I did this all with the help of the Air Force, which has never been the perfect environment for me but at least gave me some structure and a steady paycheck while I figured out what I wanted, not to mention forcing me to stay in shape.
SO, all in all - pretty damn lucky. Looking to pay it forward.
