The most major upgrade I've done in my life to date was when I got hired at my previous company
My first job out of grad school did a decent job of updating my income. i went from making 40K as a contractor to about 70K as a full time employee over the span of 4 of the 6 years i worked there. Then i started hitting a professional ceiling and the people that were pushing me along in the company were replaced by people who didn't seem interested in moving me up. Which was crazy because only a handful of people had my actual degrees in the company. It led to a lot of internal problems within my relationship with the higherups in the company and the customer base. Problems that had me pissed nearly every fukking day. It took me a while to find a new gig.
There was a company that had a position open - a Business Analyst position - was something I had turned down twice for interviews by HR because I didn't sound like something for me. Third time they hit me up, I was like why not? Because i was reaching that level of desperation to leave. Did a phone interview and one in person. Got the job all in the span of 9 days. That job levelled me up. I was in my early 30s when i crossed the 6 figure barrier. I got paid monthly so my direct deposit looked crazy

. My health benefits were top tier. I got 4 and 5 digit year end bonuses. Quarterly performance bonuses. A corporate credit card. I paid down debt like crazy, car note paid off, got my portfolio in order, savings in order. When I finally felt I could splurge a little after doing all that, man i treated myself

. Multiple vacations with my ex. Trips to go see fights. I was eating so well. Making the money I was making did lead to dealing with corporate bullshyt down the line and I left after 4.5 years but it got me to where I felt I needed to be at that point of my life and also to move forward to eventually my current job.
