I know this thread has been going on for quite a while, but I thought I'd chime in for those that come across it in 23810.124 years time and find it potentially helpful.
One value I live by is my "window shopping" mantra;
If I walk by something and immediately want it, I'll wait because doing something on impulse isn't always the best idea and I might not enjoy it at much. If I walk by it again and again and then I still want it, then I'll value and enjoy it more than something gotten out of impulse.
I have always had a general interest in health (dent/med/psych) for as long as I can remember. I came to a crossroads in my final years of high school/early 20's and almost impulsively took a creative career pathway, ultimately becoming a classroom music teacher and teaching both high school and primary. Whilst I enjoy being a music teacher, I would like to learn about health topics like surgical procedures, pathology, up and coming breakthroughs in medical science, etc (mostly wiki scrolling). Whenever I would think about gear-shifting careers, I tried to put things into perspective as I am privileged to have a good paying stable job doing music, especially the interactions I'd have with the kids as they learn. With that said, I would still have these thoughts in the back of my mind to pursue dentistry, with med and clinical psych being backups (yes, we're order and weird gear shift from music teacher). I likened my thoughts to my "window shopping" mantra and decided it is something that I need to following as I would continue to have my interest piqued.
At the age of 30, my girlfriend was studying medicine. I would look at her textbooks and topics, often accidentally learning things whilst helping her study/flicking through her books. At 31, I decided to pursue dentistry by studying an undergrad for a good GPA. Since then, I have had numerous life hurdles and situations that could be likened to a black comedy. Each time I get knocked back during offer rounds or get a poor entry score that limits my application for the year, I get disappointed but the drive is still there to go for dentistry. I am currently 34 (nearly 35) and I will keep trying to get into dent until I hit a brick wall, at which point I will consider med or clinical psych pathways.
Long story short, if you are fighting your mind to stay in whatever it is that you're currently doing, or you have something that keeps calling out to you, feel free to use my "window shopping" mantra and it may help you make a more decision that has long-term satisfaction.
Hope that my post makes sense and helps whoever is reading this
