Nostalgia is a seductive liar. People tend to get so wrapped up in how good things were that they forget how good things are now. We make ourselves forget all the bad times and dwell on the good in order to have a cushion to fall back on when things in the present get rough. So if memories threaten to get the better of you, look at the past and the present from all angles – the good and the bad.You can learn, no matter your situation. Perspective is more valuable than many people realize.
