Ten million USD in 2024 is more than enough for me and my family to live out comfortable lives, to be honest. I’d just take that, live off the interest. It will present its own problems, of course, but I’m sure I can figure those out.
Going back in time with any specific goal or intent (like making lots more money than ten million dollars by 2024) is almost certainly going to end up being its own kind of hell in this situation and especially so when there’s no guarantee that I’ll actually be successful in that pursuit. No guarantee that I’d arrive at the new 2024 with more than ten million dollars, no guarantee I’d be able to “fix” anything without causing worse problems for myself and others, no guarantee that I’d get here alive again, sounds like quite a bit of a risk.
Plus, once I go back to age 6 and start making different decisions, a different future will necessarily emerge. Think about it this way, in order to not change the future (until you’re at a point where you can reasonably execute a plan to reach your goals), you’d have to make exactly the same decisions you did when you were 6. Pretty much nobody has that kind of memory/recall, so it would literally come down to sheer luck. And the further along in time things progress, as you make more and more different decisions than you did originally, the more uncertainty it would introduce to the new future. Eventually, you may even find that you basically have no more ability to recall/predict the future than you would have otherwise.
So if you’re in it for the money, just take the guaranteed money.
