I really got into planning it for a while, and have had intricate procedures I have wanted to follow. But after a while, I got to realizing that when I die, I could be penniless and devoid of friends or family. 2 people might show up out of obligation, so why make them sit through a bunch of readings and, like, 5 songs. Simple suits me.
