Kate, first Nancy provided some excellent info. Don't worry if you do not "get it" the first time. As you play the game (and visit this forum) it will all become clear to you.

Definitely visit the link that she provided. You will find a detailed explanation on professions. Meanwhile, here is an abbreviated version -
 * 1) Magician (symbol - lightning bolt): Decreases energy points needed to investigate picture/puzzle
 * 2) Merchant (symbol - coin): Increases coins earned from successful investigation of a picture/puzzle
 * 3) Sage (symbol - star): Increases experience earned from successful investigation of a picture/puzzle
 * 4) Sleuth (symbol - camera):  Increases chances of finding items. Note: Sleuths increase your chances of receiving rewards for successful investigating a picture or a puzzle the same way that luck talismans help you. They do not help you find items within pictures during investigations.
