Go to theological college become an ordination member of the clergy, perform magic during your sermons while claiming to be Jesus, (Proof? You can do miracles!) become the next Jim Jones, start a magic camp in Guyana...but you'll only teach people key card tricks (because if you give them all the methods they won't need you anymore...and we can't have that.) for 3 years, and it won't even matter because they will only have each other to perform them for, because they left their families for your teachings...and they could show you, but you banned anyone showing you magic effects because it would be insulting to you all knowing, all powerful intellect.
Then 2 years afterwards do a mass vanishing act, in which you yourself do not actually vanish...no, you stay behind and claim it was rapture but you came back to help those who are lost.
Retire, move to Martha's Vineyard...the end.
Alright, I'm kidding...don't do that. I think a degree in psychology would be a great advantage concerning magic, it would give you an edge dealing with people, plus put an interesting twist on mentalism effects if your spectators knew you had a background in psychology.
