YES! YES! YES!
My spreadsheets have been very good to me lately! All my long-term calcs are done on 5% return (3% inflation), and in my DH's IRA we already passed the goal for 2013!! ...so if we can just hang on to that gain for the rest of the year.
Whenever I start feeling a little impatient, annoyed, frustrated (insert adjective here), I just break-out my spreadsheets and reflect on the fact that I have less than 3 years and then my world of opportunities open up.... work part-time, contract work a few months per year, small business, stick it out 2 more years and then be completely done.... the possibilities are endless.
....ahhhh, marvelous spreadsheets!
