Every amusement park has a roller coaster. People seem to love the feeling of unpredictable changes of direction, swooping up, then having the world drop out from under them. The most spectacular new roller coasters even have helical tracks, that spin the riders upside down. I hate roller coasters. I always have.
Life has enough ups and downs.
When I was growing up, my family wasn't affluent. I observed the value of savings when trouble hit, when I got a rare blood disease at the age of 16. My parents' wisdom, and the ability to pay for the best doctors, pulled me through. You may be lucky, and have a nice, long upward pull that never ends. My long-term strategy is to live well below my means during my earning years, so my lifestyle will not have to change in times of trouble or after I retire.
