From rags to riches? lol Robert Downey's old man was an actor, if not mistaken so was Johnson's old man a celebrity wrestler too. Far from motivation if you're suggesting both of these two grew up in poverty and in the hood, lol. Like both of them regardless and Robert Downey Jr did make one hell of a comeback! He was already talented, really all he did was have to get off the drugs... Which I guess aint easy for some people!
