That doesn't make it any less feasible if you find yourself dissatisfied with your current path. Just don't fall for an illusion of greener grass on the other side of the fence.
For a personal view: I was programming in BASIC at 12 and coding HTML not long after. And while my professional journey has been... meandering (I'm whatever the opposite of a Type A personality is), after 10+ years (not contiguous) of having some variation of web development as my primary job responsibility, I'm pretty well bored and unmotivated at this point. I've made more than I do now and been less happy and I've made less and been happier, had more/less autonomy, and in a relatively wide variety of environments: large corporation, small businesses, not-for-profits, freelance, healthcare, verticals, consumer-oriented.
And frankly, if I had ideal working conditions and made double what I do now, would I happier in general? Sure. But I wouldn't necessarily be any more excited to wake up and do that work than the day before. Because the factors you cited, while not inconsequential, can vary and change due to factors entirely out of your control. And they have no causal relationship to any particular work.
In other words, if you've eliminated all bureaucracy and office politics from the equation, and you secure a generous income, it still doesn't mean you'll feel different when your head hits the pillow at night and your eyelids lift to greet the morning.
With a 12-24 month timeframe, you may want to reflect on what your core values are—what really drives and motivates you.
