"If I waited for perfection, I would never write a word." You don't achieve perfection the first time you write. You attain it through writing and rewriting and going over and over again your chapter. Don't expect perfection... Attain it.
There's a whole lot I can't do right now during this sickness. But, I can still be mom and wife who hugs, listens, talks, encourages, laughs, solves problems......I can even sometimes play a game or read them a book. I can can also pray, and I can praise.
