Just make sure they learn to recognize the value of trans-material assets: one can loose their financial wealth in an instant easily, but their reputation, skills, knowledge, intelligence, health, psychological capacity, inner dignity and freedom of compassion, unconditioned vision and decision-making are less volatile. Understanding this is the first step upwards and is enough for many. Eventually, as the consciousness develops and matures a subject can also recognize these assets are also volatile and seek forth to meet their true self that actually owns these and is the only reliable invariant in their subjective universe.

At the same time try to avoid values dichotomization so the kid won't grow up with a destructive idea of financial wealth being a bad thing to pursue.

If their intelligence seems not sufficient try to make it fun for them to play n-back games like BrainWorkshop, their intelligence will develop stronger and my experience suggests it helps to grok all kinds of stuff (including even transcendental matters!) a lot, in whatever an age (it in fact has enhanced my own mind capacity enough to instantly realize that life in a society is not a zero-sum game and it is usually more beneficial for myself to help others to develop, succeed and strive than to care about maintaining competitive advantage over them and that in whatever an argument the primary objectives are to understand the opponent (whatever bizarre they may sound and regardless to whether or not they're wrong) and enrich your vision while winning the argument is a secondary objective and even happens to be irrelevant in many cases).
