Sklansky-esque super-human question: Memory

[Magic_Man]

I am wondering about the advantages of certain specialized skills, and DS's posts in his forum have got me thinking about some hypotheticals. Here's the first one:

After an explosion at the chemical plant, Joe wakes up the next morning to find he has developed an eidetic memory. He remembers everything and anything without effort. He can recite any book verbatim after one reading, or easily recall any segment you choose. He remembers the name and face of everyone he meets. Etc. The first thing he does is blow away the world record by reciting pi to 250,000 digits.

However, assume his other mental skills are of a moderate level. Say a decent public college education. OTHER THAN doing an explicit "memory man show," how can Joe best use his new skills to:

1) Maximize his income.
2) Maximize his happiness in life.
