Yes, we do have a clue. Get at least a high school education. Do not have children until you are married. Stay married. You will not become Bill Gates, but you will not live a helpless life. The problem is, this requires too much work and responsibility.
And, don't get married or have children, either as a father or mother, until you are past the teenage years and are willing to commit yourself to them and remained organized, so you can stay out of jail, keep a job, and stay sober, and you will never be poor.
What do you think "get a high school education" should consist of?
Do you mean show up and don't get expelled?
Or do you mean 4 years of English, 3 years of History, Math through Trigonometry, Biology, Chemistry and Physics, and mastery of one foreign language?
Here's a fact: In 1941-42, the percentage of whites at age 18 who "got a high school education" was 25%.
The native ability to "get a high school education" is probably not much higher than that.
