OK, so, my first advice is to chill. Your kids will learn more from what they see you do, day in and day out, than from anything you tell them.
Second, believe me when I say you have absolutely *no* idea what kind of kid you will get. When I think back to what I assumed my kids would be like, and how I would raise them and train them and this and that, well, I can only laugh at my own hubris. My kids came out of the womb who they are; there is no power on this earth that was going to change that. The most humbling thing about parenting is realizing how little power you actually have to "mold" your kids in the ways you want and to keep them from making the same dumb-ass mistakes you did. If you have an artistic kid, you cannot turn that child into an engineer, no matter how much you try; all you get is years of pain, a terrible relationship with your child (who is smart enough to know that Daddy doesn't love him because he isn't good enough at science/math), and a total crash and burn.
Kids are going to be who they are, so what you need to do as a parent is to take the time to really learn who that is -- not who you want them to be, but who they are down deep, what their strengths and weaknesses are -- so you can then help them build on those strengths and convert them into useful, employable skills. E.g., if you have an artistic kid, don't force them away from the arts, help point them toward "art that pays," like graphic design, working for advertising agencies, etc. Broaden your own view of what is an "acceptable" field, so you can help your kids navigate to areas that make the most of their talents while still paying reasonable wages. Yes, "follow your passion" is bullshit. But it is true that your kids are most likely to succeed by building on something that they are already good at and enjoy, vs. something they can be marginally adequate at with a lot of effort.
And please do not assume that just because you learned to love something because you stuck with it, the same will be true for your kids. Your kids will be many things, but they will not be you, and what worked for you may not work for them at all. There are many, many people in this world for whom being forced to stick with something they don't like is a version of hell, and who will not learn to like it no matter how good they get at it. I am one of those people. Grit and resilience are awesome characteristics to build, but for many people are insufficient to fundamentally change what they enjoy.
Finally, always remember that you catch more flies with honey than vinegar. Your posts do tend to come across as authoritarian, as you are the dad, and you know best, and it is their job to listen to your advice and do what you say. All I can say is that most kids who have any kind of a backbone rebel against that kind of approach. So, you know, if you want to push your kids into the arts, the best way to do that may be to shove STEM down their throats. Listen again to what some of the earlier posters said: your goal cannot be to raise kids who make a certain specific decision -- it must be to raise kids who know how to make good decisions. But the only way kids can actually learn how to make good decisions is to be given the freedom to make some bad ones along the way -- preferably long before they are being asked to borrow $200K for college. The more headstrong your kid, the more you need to back off, provide education and guidance, and then let them go. I think of myself as sort of like rubber bumpers along the side of the road -- my kids may bounce around six ways from Sunday while they figure things out, but as long as they are heading in the right direction and I am keeping them on the road, then I'm doing my job.
Oh: and have a little humility about your ability to identify the Jobs Of The Future, too. There were a lot of trades going begging during the last housing bust, and there are a lot of petroleum engineers looking for work right now. And some of us former English majors have -- miraculously -- managed steady employment and jobs well into the six figures. I know, go figure.
