@GwenDR , I was also thinking, for example, I always wanted to work with those in a particular developing country- 30 years later in many ways I still do. So it's being true to yourself- many people say they reach the top of a ladder only to find it's the wrong ladder.
But someone said here once (I'm sorry I can't recall who :( ), if you can identify what you want or like about something, then you ask yourself, 'what other ways can I possibly achieve that?' And that is not to say you won't finish the schooling, but who knows where your path will lead? And I have to admit, though I'd rather have more financial resources, to give, especially, there are many times and many reasons I'm glad my path diverged.
On top of that, it sounds woo-hoo, but I have an interior reason I offer up, no matter where or how I am or what I'm even able to do. It may be worth nothing, or it may be worth something, Idk.
Nothing you ever learn will go to waste. I remember being really good at mouth-pipetting in science (it was actually not allowed, but I was super-fast and accurate), it came in as the only solution in a crisis situation no one could solve, about 5 years later! The journey can be as important as the destination, please don't lose heart and try to recognize and try to give yourself credit not blame, for all you are accomplishing, every day! :) :hug:
