Better try 'passive investing'
i cannot tell you much what to do,
but surely what not to do.
you can find it here, just my own thinking:
when you can bear the risk of stock investing, and can let work the invested funds for 20 years without touching/selling them, and you look for a hassle free solution with presumably decent returns, maybe
MSCI ACWI ETF (tickers SPYY/ACWI)
is a good first choice.
