Howdy! I'm Spencer, an active-duty Air Force officer investing for financial independence by age 40. Since 2016, my wife and I have saved half of my active-duty paycheck into our financial independence accounts. I started writing in 2012 about achieving FI in the military on my website Military Money Manual.

Because J.D. has no experience with the military, for Veterans Day he asked me to share the lessons I think every servicemember needs to know about getting rich slowly. These are the concepts I wish someone had explained to me as a newly-commissioned officer in 2010. (These lessons are just as applicable to the enlisted side of the house.)

I've split this article into two sections.
