I'm just now seeing your question, M. The first thing I thought when I saw it, is that I don't have any third world problems, so all of mine MUST be first world problems!
I do think that it's okay to be light-hearted about some problems. There are so many serious ones on this site with moms far and wide. And there are so many world problems as well. I think about the kids who don't have enough to eat and their moms here in the US who struggle to make their grocery money stretch so that the frig isn't empty before the week is out. As an adult, I've never had that happen in my house with my kids. I do remember my mom telling me that she and my daddy ate hot dogs so that us kids could have the more healthy food when we were little, because they didn't have much back then.
At this point in my life, I know that if my husband and I retire in 5 short years, other than health insurance which we would have to buy, we'd have as much to live off of after retirement as we do now on a salary. Luck and good planning have been our friend, even with the terrible downturn with the economy 4 years ago. I'm grateful for that, though we certainly won't be retiring in just 5 years. One needs a goal in life and to keep one's mind young! In 5 short years, our kids will be done with college and will hopefully get decent jobs and live and manage life on their own, with no college debt. Another thing to be grateful for.
I might consider it a problem to have to manage taking care of things like the shower plugging up because my hair has gone down the drain, and the kitchen spigot working its way loose (another plumbing bill), but I'm also contributing to the economy by giving someone a job so that he can feed his family.
Gonna make my hair appointment to color my gray - even though I hate gray hair on me, at least there's a such a thing as hair color so that I don't HAVE to have a problem with gray hair. Yippee!
My highschooler has had such a hard time with his pre-calc. His poor grades were definitely a problem, demoralizing for him and stressful for me. I hired a tutor (a cute highschool girl in AP Calc) and she is helping him understand the math. He made a 90 yesterday on his test. Hurray! I'm so happy for him and grateful that I found a solution to THAT problem. (And the tutor is such a sweetheart!)
So basically, I can't think of any of my "problems" as problems! And I feel grateful and blessed because of it.
Life is good!
