Maybe not, but knowing what not to do (as if you didn't know) is a good start.
I would say, at the risk of being pedantic:
don't invest more than you can lose without batting an eye, especially if it's a very risky investment that can go to close to 0.
Put 1/3 to 1/2 of the money that you can comfortably miss in a broad index fund (based on something like FTSE ALL-WORLD), put the rest in when the stock market tanks completely (-1/2).
Don't take out your money when the stock market tanks. Put in more.
Buy the index. BUY THE INDEX.
I wouldn't take investment advice from this place, Wall Street Bets, or anyone really.
That's not really much to work with, though.
