Sure, your formula is not wrong. But its a bit like saying "it's easy to lose weight, eat less, eat better, exercise more." It might be simple, but it's not easy.
Going into the nuance of each step in your formula would result in a too-long post, but let's consider the first;
>> stay in school, pay attention, get good grades.
For various reasons this is easier to do for the rich, and harder for the poor.
Better nutrition.
Better home support if your parents were educated and have surplus time.
Better access to ancillaries (books, stationery etc.)
Less need for you to get a job to supplement family income.
No need for you to act as day care to younger siblings.
More reliable transport to and from school.
Better sleep patterns in warm, secure, environment.
Better infant nutrition resulting in well-developed current mental facilities.
Better access to heath care, meaning fewer lost school days.
And so on.
Your formula is not wrong. But it is not easy. And every part of it is greased with money. The best indicator of success is the environment you are born into.
It's worth stating clearly: the best predictor of poor health and other "failure" is being born into poverty. A predatory economic system will defend predatory economic mechanisms.
Such a system will even go to war to defend the "proper order of things".

I agree you have choices. It's just that those choices are easier, and simpler, the more money you have.
Incidentally the drug choice is less aligned with poverty. Middle class and rich people take plenty of drugs, including expensive ones like opiods and cocaine. Drugs more likely to be used by the less affluent (weed) is more actively enforced, including well understood disparities on racial and socio-economic lines.
But we digress, this is not about drugs. It's about the ability of people to succeed. And the playing field there is far from level.
So don't smoke weed, and disparate enforcement won't matter.
I voted for the legalization of marijuana. That doesn't mean smoking weed is a good idea. It's expensive, too. Can't really claim one can't make ends meet when spending money on weed.
