Which age did you achieve financial milestone 100K, 1M and current net worth in SG?

As in the title. I wander the thoughts of which age I should be expected to achieve some of the financial milestones in life, so I would love to hear your stories.

I heard people saying that the first 100K is the hardest one to get, how about from 100K to 1M? 1M to more? What’s the time gap between these milestones?
