A new study published in Psychological Science finds that it is healthier to let go of a cherished goal that is most likely unachievable than to stubbornly persevere against all probability of failure.
[P]sychologists followed teenagers for a full year. Over that time, individuals who did not persist obtaining hard to reach goals had much lower levels of a protein called CRP, an indicator of bodily inflammation. Inflammation has recently been linked to several serious diseases, including diabetes and heart disease, suggesting that healthy but overly tenacious teens may already be on the road toward chronic illness later in life.
Accordingly, Miller and Wrosch suggest it may be more prudent to cut one’s losses in the face of an insurmountable obstacle. “When people are faced with situations in which they cannot realize a key life goal, the most adaptive response for physical and mental health may be to disengage from this goal,” write the authors.”
