I mean that answer entirely depends on the year I "become" him.

Birth to early 1900s? I would've stayed out of both art school and WW1 and fucked off to America; or literally anywhere except staying in Central Europe.

1939? Avoid needlessly depleting the Luftwaffe in the Battle of Britain and put off the invasion of the Soviet Union for as many months/years as diplomatically possible, to consolidate the Western European and North African theaters.

1944 or later? Order as much amphetamine and tight German teen pussy delivered to my bunker as is remotely feasible, and bang it out/do meth until I eventually die of an overdose of the one or the other.
