I recall preparing over two Olympic quadrennials to get ready for the 1980 and 1984 Olympic Games.
I trained as a shooter for the boycotted Moscow Games (a team I did not make) and the Los Angeles Games (which I did make and later medalled in). It was not a financially comfortable time in my life.
I supported myself with a mix of funding from the G.I. Bill, a graduate assistantship teaching physical education classes, and work as a shooting coach. I also served part-time as a member of the U.S. Army Reserves. All told, from working three jobs, I earned $500 a month (around $1,500 today), plus the cost of tuition.
