I will truncate my early history, but an important foot note is that while I have always been interested in health and related fields, I had dropped out of high school so the idea of entering any allied health field felt like a pipe dream.
Life leads in twists and turns when you let it, and I ended up running a record label for a few years before finding myself managing for a large music retailer in various stores around the US. I had not really enjoyed it the entire time and many of my mentors with the business regularly told me I was wasting my talent in that business, which I think may have helped rebuild the confidence lost from prior academic shortcomings. After spending 2 years developing a new position with the executive team at the corporate office the salary had finally been approved, but a week before the offer came in I had decided to resign and go back to school and start over from box 1...
The reasons were not as cut and dried as your typical "PT changed my/someone I loves life". It was more an issue of me loving anatomy and physiology, being profoundly interested in health in general, and being honest with myself about my interests, motivations, and emotional capacities. I looked really hard at MD or DO, but I do not really like pharmacology or western medicines tendency towards pharmacological interventions, and if I ever found myself in an emergency room rotation I absolutely do not have the emotional strength to deal with a parent bringing in a lifeless child. I also really appreciate the 1 to 1 time that some fields of PT get, and I like to see someone more than once to watch the results of our work accrue. I believe that motor function plays such an enormous role in individual happiness, productiveness, and overall well being... And there is no doubt that a single individuals attitude and actions can have a resonant effect across a community.
So in the end PT ended up aligning most with my own motivations and interests, so here I sit 2 months away from finally putting in my application to grad school.
Money certainly was not a motivator - I can only hope to make as much in PT eventually compared to what I walked away from when I resigned... But as stated before, when you spend 60 waking hours in a week in a position where you are unhappy, stressed, unable to disconnect.... The money becomes secondary to happiness. You begin to look at existential questions like "if I died tomorrow what would I do today", or "what will people say at my funeral, what will I have accomplished in my life"... And for me those questions were heavy enough for me to take the risk and jump careers.
