Nostalgia is your remembrance of the things in the past, not necessarily as they were in reality. Nostalgia is often negative, and yet it can sometimes trigger a positive phenomenon that works exactly in reverse. Nostalgia can lead to strong yearnings for discovering new lands, exploring newer oceans, and offering your unlimited creativity in most unfamiliar spaces - everything that is beyond your normal limitations, and outside your comfort zone.
