This weekend, after listening patiently to my angst, a close friend told me to write down what "enough" looks like. (I had been complaining that I didn't know how I was ever going to do enough of all the things that I needed to do. This is subtly different from the problem of taking on too many tasks, although I have that too - I've been working on that problem and balancing things out with some success! But now I am worrying I'll never be balanced enough...)

She suggested writing because I process best by writing. Some people process best in a conversation, or through other methods.

The key to this is that you write it, and then you look at what you wrote with a grain of salt. Is it realistic, or are you beating yourself up for not achieving some fantastical, pie-in-the-sky, I-want-to-be-the-very-best ideal?
