One of the common mistakes I see is that most underestimate the money save by not going to work. My sis is really smart and when the Gov of NY asked her to head up a department 4 hours from where she lived instead of retiring, she ended up having to rent an apartment and do an 8 hour commute home and back on weekends. Kept saying she couldn't afford to retire. When she got tossed under the bus she did retire and saved $15k/yr right off the bat. Now her and her husband travel a lot with that money and all the extra time. What she really stayed for the the rush of the job and feeling needed.
