Arguably the most important Side Quest to complete is Mount: Donan's Favor, which unlocks Mounts at Stables around the world and significantly boosts your movement speed. This quest only involves interacting with NPCs and is unlocked automatically as you progress through Act 4.
Unfortunately, there's no way to access it early, but once you've progressed through Acts 1-3 and reach Act 4, be sure you don't miss this one.
