Write shit down - that's what I do - and it motivates me to stay the course.
Last night I scratched down in my "finance notebook" my savings, DRiPs, Brokerage, IRA's, Roths, and 403b balances from December 2013 then compared them with December 2014 numbers. Yes, I have all this in electronic spreadsheet form, but there was something very therapeutic about writing these numbers down in my little composition book.
I amazed even myself b/c we spent much of 2014 killing our mortgage and my husband has been FIRE'd since June 2013.
End result: we contributed $43,800 into the aforementioned accounts and they gained $22,900 for a total increase of nearly $67,000. That's my annual gross salary! Holy cow. The power of compounding is remarkable.
Try it, it might help you refocus, re-energize, and re-commit to FIRE. Plus these message boards and encouragement from fellow mustachios keeps me going!
Good luck!
