A comment left today on Toward Jerusalem forces me to spell out on this blog the following inventory of my life's "phases" - all occurring after 4 years of military service during the Korean war.
Peace officer/supervisor 5 years
Automotive service adviser/manager 6 years
Weekly newspaper editor/photographer 3 years
Solid waste business manager/supervisor 5 years
Transportation manager/supervisor 11 years
Retail/Advertising sales 4 years
State DMV technician/license examiner/manager 17 years
Others may see some type of trend here, but each of these fields were different enough that they challenged my interest and intellect while providing an acceptable level of living for my family. And for all of that I thank God.
As to the question "could I have done 'better' just sticking to one field?", I have no way of knowing the true answer, but my feeling is that only a couple of them might have qualified in that category, and at this point in life there is no sense worrying too much on that point!
Don't be afraid to redirect your interests. God has a way of using you whereever you decide to be. And it's fun to s-t-r-e-t-c-h your mind!
