As of this week, my 401k balance topped the $200,000 mark for the first time.
I started this account when I started working here per diem in April 2016. I went part time in February 2017 and full time in November 2017. I contributed the maximum allowed in 2018, 2019, and 2020.
So 200K accumulated in under 5-1/2 years. Not bad at all.
