Life's too short for bullshit. You know when you see it. Bad jobs that won't go anywhere. A relationship or commitment that your heart isn't into. Once you identify it, get out ASAP.
Find something that is exhausting but you'd rather not do anything else. For me, my sweet spot is in business growth, startups, user flow, modeling the real world into data, training (which melded well with working with NLP/AI).
It involves software a lot, especially being able to build things, but there's a lot of jobs that pay well but would be ultimately unfulfilling for me. Yours is probably different.
Some people call it passion, but the misconception is you won't be entirely passionate or dispassionate about a whole field. Rather there will be patches of interest that you hook on, like a mountain climber and handholds.
