Oh-ho-ho, so it's the get-all-the-powers-in-the-cosmere thread, eh? In that case, I was born near Elantris, and became an Elantrian, somehow hacked my way into the other forms of investiture there, travelled to Scadrial and ate some lerasium and then stole all of the feruchemy powers, stole all of the honorblades and proceeded to use them at any time to access all of the ten surges, then ate that other thing that lets you become a voidbringer for good measure, visited the nightwatcher and asked for some epic boon, and somehow avoided the curse, went to Nalthis and collected about 5,000,000,000 breaths and used them to awaken a bunch of metal, hacked my way into Sand Mastery, and the Sixth of Dusk thing (still haven't read the book), then went on a shard murdering spree, thereby gaining all of the shards and becoming Adonalsium. Oh, and for good measure I broke the rules of the cosmere and went to Earth and hacked my way into being an epic.
