One thing that comes to mind is from when Levi was a baby. He was a very sad baby--I think he had reflux or something--and cried at the least provocation. He constantly was demanding my attention, and I had little time to do anything that wasn't with him. There was one point where when he napped, it was hardly ever more than 30 minutes at a time.
I was constantly frustrated with not being able to get things done. I was not experiencing very much joy; mostly I was experiencing a screaming child and not being able to do the things I wanted to do.
Finally, I took an honest look at my life. I knew I was frustrated, and I knew why. I finally said to myself, "Self, things are not going to change anytime soon. Self, what do you need to change about your expectations, and what do you need to change about your life to get the things done that you need to?"
My first change was my expectation about what I could get done during a 30-minute nap (not much). When I started expecting things that could realistically happen, I stopped being as frustrated about not being able to do the not-as-doable things that I expected to do before.
Another change was in my style of doing things. Previously, I did everything in big chunks. I set aside some time and "got 'er done!" After honestly looking at the time I had all at once, I knew that wasn't practical. I started teaching myself to do things piece by piece and to multitask. It has been a long process, let me tell you!
I saw immediate results. I didn't get as much done as I had before having a baby (surprise! haha), but I was able to get the things that needed to be done, done. The new way wasn't as efficient as the old way, but I was happier. Constant frustration was gone from my life (periodic frustration remained, of course), and nothing about my circumstances had changed.
