“Consider this scenario.

You own shares in Company A. During the past year you considered switching to stock in Company B but decided against it. You now find that you would have been better off by 1200$ if you had switched to the stock of Company B. You also owned shares in Company C. During the past year you switched to stock in Company D. You now find out that you'd have been better off by 1200$, if you kept your stock in Company C.

Which error causes you more regret? Studies show that about
Immune to Reality nine out of ten people expect to feel more regret when they foolishly switch stocks than when they foolishly fail to switch stocks, because most people think they will regret foolish actions more than foolish inactions. But studies also show that nine out of ten people are wrong.

Indeed, in the long run, people of every age and in every walk of life seem to regret "not" having
done things much more than they regret things they "did", which is why the most popular regrets include not going to college, not grasping profitable business opportunities, and not spending enough time with family and friends.”
