People who retired before 35, how did you do it and what was your target NW number?

Hello Everyone, I have been lurking on FI for a long time now. I am in my mid 20s and on the path to FI (I Think). My goal is to retire by the time I am 35 which is still a little far. I wanted some insights from people who have retired before they turned 35, what was their savings rate, how much they invested in non taxable accounts, did they buy a house etc. I am also interested in finding about your target number at which you retired?

My + Wife's combined NW currently is $250k + (50K gift) - ($15k debt)

Both have full time jobs. (110K combined salary)

We max out our ROTh IRA each year. and contribute about 25% to 401k. (Hopefully 2017 is our first year where we are able to max our 401k as well.)

Thank you all in advance for taking out your time to answer my questions.

EDIT: I would Like to thank all of you who commented on this tread with their valuable input. The information helped a lot and I learned that every person has their own specific goal, no one is absolutely right on what the end NW figure should be it depends on the person's spendings and their living situation. I wish everyone good luck in their journey to FIRE.
