If you want your life to change, wait a year. It’ll change. Of course, it may not be for the better.
A study in 2008 found that happiness tends to follow a U-shaped curve, where the lowest level of happiness occurs somewhere around age 46. Yet, there are confounding factors. A death of a spouse, child or close family member, divorce/marital separation, imprisonment, personal injury or illness, or loss of meaningful work can all contribute to shifting our nadir of happiness into a different period. But, knowing that the 40s can be a difficult time, on average, and that life tends to improve after can be a helpful thing to know. It can be a source of hope.
Nothing is sure in this life but change. Are things difficult for you? All you need to do is wait. It’ll change.
