I'm fortunate enough to work at a place that offers a 457 plan alongside a 403b and I just did my annual run through to make sure we weren't going to go over on any of our contributions (wife has a 403b, our Roth IRAs) . Due to a job change and two raises I am far closer to maxing this out than I thought I would be. That doesn't count the 3.5% my wife contributes towards her pension which is supposed to be there when we retire (not holding my breath).
I have no doubt there are many badasses on here doing even more but I'm pretty happy with those numbers at 33. I also like how small our tax bill is
