​So devastated, one third of my retirement fund was evaporated.

While originally, I thought I could retire very soon, it was in mid-2007; my retirement fund grew so well. 

Just shortly after, the market crashed; more than one third of my retirement fund was gone. 

Fortunately, I still had a job, still have time to accumulate my retirement money and did not have to retire for another 25 years.

But​ what if this could happen again when I would be ready to retire or after I would have retired.

Should I postpone my retirement? Or should I still have time to accumulate my wealth?
