A Dark Room: From Sabbatical Year to $800k
The math on this makes no sense at all.>- Live off of $15k a year. Don't buy a house. Don't buy a fancy  car. Just save.- Do this for a year.- Land a job that makes you $100k a year. Save the rest. Max out your 401k contribution.- Celebrate by living off of $30k a year.- Do this for three years.- Land a job that makes you $140k a year. Save the rest. Max out your 401k contribution. Get a Roth, put $5k a year into that.- Celebrate by living off of $60k a year.- Do this for three years. 
>He is talking about SAVING, $500,000.  Then needing to liquidate your 401k, just to take off a year?If he is capable of living on 60k before this, he should be able to live almost 10 years just on his savings without liquidating the 401k.
