Wikipedia definition of Nostalgia:
Nostalgia is a sentimentality for the past, typically for a period or place with happy personal associations.
Nostalgia is associated with a longing for the past, its personalities, possibilities, and events, especially a “warm childhood”. There is a predisposition, caused by cognitive biases such as rosy retrospection, for people to view the past more favourably and future more negatively. When applied to one’s beliefs about a society or institution, it’s been described as “an emotional strategy”, something comforting to snuggle up to when the present day seems intolerably bleak.
Nostalgia to me:
These are things that make me think of my childhood – I thought I’d recreate this reminder in a Moodboard of things that I think of when I’m asked about my childhood.
