As you progress through the game, you unlock a series of optional sidequests. To find and trigger them, explore town areas (especially pubs) and talk to highlighted townsfolk you meet. Some will ask favors of Rush. Each favor is a side quest and usually requires the completion of one or more tasks. Complete these tasks to earn rewards. The tasks listed here may appear one event earlier or later, being as how the Walkthrough is broken down. Good luck and keep in mind the missable quests!
