I’ve looked into it, that’s dangerous advice. In most timelines, it leads to a chain of events where Dali melts 80% of Spain’s population with a bioweapon/art project. It’s very complicated, not a straight line shot, as best we can determine, while attempting to pursue a career in the field, he does some columns for a newspaper critiquing art, and says something about some artist that somehow influences someone who somehow influences Dali. Hard to unravel because the historical documentation on the nobodies is so spotty.
I mean, the plan CAN work, but immediately after Hitler graduates art school you have to hook him up with, and make sure he impregnates, a poor girl so he decides to get a more respectable job to support them. Then you have to get him that respectable job so he doesn’t find somebody to blame his lack of success on.
And, I dunno, making a mission of getting Hitler laid and then well-employed seems to turn off a lot of prospective time-alterers.
