Regarding the bold...
Do you remember when we used to watch Rangers games together on skype while I was traveling, 2013/2014/2015? At 26/27, I was VP of a $12 million dollar division. I was living a crazy life, constantly traveling, got to stay in expensive hotels, had an expense account, got great perks, was always out with the CEO/COO at dinners and such, money was rarely ever an issue... I was living the dream at a very young age. Only it was the dream of someone else, not me. I thought it was what I wanted. I was miserable. Flat. Out. Miserable. I held on for so long because I knew my family and girlfriend/fiance (now wife) were so proud of me. My friends were absurdly jealous. Many of them just moving out of their entry level jobs they had taken a few years back.
I resigned in early 2016, took a different role with the company and a few months later left to go work elsewhere as a recruiting manager, a major step down for a Home Health VP, going from working on meeting our EBITDA goals and living in financial reports to.. working with resumes. I thought I was going to disappoint everyone. My degree was in finance. I was running **** a young age. It seemed to fit and it was "smart". But when I told my family and then wife what my decision was, they knew I was happy and they supported me. It was a drastic, and I do mean drastic (50%) pay cut but I couldn't stop smiling and knowing that they all supported me, it made it that much easier. Not to mention, this job has been a happy accident. I have been able to learn a lot more about HR than I previously did and in addition to recruiting, I now oversee employee relations, performance management and leadership development, three things which I absolutely love.
I doubt your family will feel as if you let them down. You need to do what is right for you. For some people, it is more important to do the work they love, money be damned. To them, financial stress is significantly less bothersome than being unhappy in their career. To others, financial stress is significantly more bothersome than being unhappy in their career. If you haven't already, I would really sit and think about what you want in the next 5-10 years? Do you plan on ever getting married? Having kids? Do you want to travel? When you figure out what you want, you can then begin to the understand the means needed to achieve those things. Whatever it is you decide, I would guess your family will be there to support you every step of the way.
