Thinking about fretting/stressing

Today I was thinking about the difference between my husband's kind of stressing and my kind of stressing and it lead to a pretty nifty conclusion. Bob frets about stuff over which he has absolutely NO CONTROL; whereas I tend to stress about things over which I think I do or SHOULD have at least some control. For example, he stresses over delays at airports/weather conditions/traffic, etc. I, on the other hand, stress if I'm running late to work because I piddled too much and left the house too late. The only stress I had about the delays today was that I have some school work to do before class tomorrow that I didn't take with me...(so you see, I was saying to myself that I should have done the work before I left OR that I should have taken the work with me so that I could get it done on the trip). Turns out that we got home in plenty of time for me to do it anyway, despite all the delays in Boston this morning.

But sometimes I, too, stress over things over which I have NO CONTROL. So what I thought about today is that when I start worrying about something, I should first ask myself if I have ANY control over the situation that I'm worrying about. If the answer is, "no" then I think I should let go of the worry/fretting/stressing.

I wonder if I can make that work for me! What do you think?
