Figure it out now? it is not too late ( refer to my post to you a few months ago).
I knew a few people who had been working hard all their life, died in their 50s and a particular one died 6 weeks after retirement and left the memory of that she had so proudly achieved 40 years of employment history for one company and enjoyed the party that the employer provided to her).
If you enjoy what you do, keep doing it. There is nothing wrong to work hard all your life to prove yourself, and it is also good for society. Don't we forget we were educated to "sacrifice our life to realize communism" when we were in elementary school?
As to your RE investment, Consider yourself lucky since you actually have not endured any hardship or market downturn in the RE investment market. We haven't had severe corrections in the RE market since the late 80s ( don't mix up RE market price fluctuation and corrects or crash( I don't have time to argue with some CFCers).
The value of all hard assets has been keeping rising and rising because we have been in ( near) zero interest monetary policy and populist fiscal policy. And globalization provided a low inflation environment for them.
Will globalization continue to provide low inflation? I think so in the short term. As raising China and overtaking the US becomes closer and closer. The US won't take anyone possibly threatening his reserve currency status advantage. War could be in our lifetime or beyond our lifetime. The card is in the US's hand so nobody knows.
Anyone could say that money is not everything, but when doing, most CFCers put the money( job) above their lifestyle (I emphasize again it is nothing wrong with it).
So I will repeat it. It is not just that health and age play a part. World peace will play a part in our life too. Enjoy your life.
