Believe it or not, human beings aren't teleologically designed; and the future is not knowable (even though some things are broadly predictable — as far as we know). (See the problem of inference / black swan problem, to start.) So no one knows for sure (in general or in your, or anyone else's, specific case).

Best we can do is heuristics, rules of thumb, etc.: ancestral wisdom based on as much time and experience as possible. Included in those — and among the most useful and reliable — are tips, not for maximizing benefits/successes, but for avoiding almost certain misfortune and ruin.

Hence: avoid harmful substances and behaviors (alcohol, drugs, gambling …); generally avoid/neutralize envy, greed, etc.; avoid killing; teach yourself contentment / how to live with life's basics / how to want what you have instead of trying to get what you want; keep an inner score card instead of a worldly, external one; care for the body; be charitable; beware tampering with complex natural systems (Chesterton's Fence); eschew superfluity; focus on process more than outcomes (what is in your control, not what is outside of it); etc.

Take care of your downside risk, and then acquire free options / expose yourself to positive expected-value uncertainty.
