I have learned:
...if life gets in the way of your writing, vacation does too. Because your schedule and activities change (when you are on vacation), you must continue to plan your writing time to be productive. If you don't, writing may not happen.
...continued learning is crucial. Along with reading fiction or nonfiction of your choice, to scope out writing styles, you also learn from reading "how to" writing articles. You can do this through books, blogs, and websites. Also, classes on writing are very helpful.
...writers are supportive and happy when other writers are published. Why? It encourages the rest of us. I've only had a few children's stories published (in the late 80's) and remember how exciting it was to get my work in print. That memory also encourages me.
...(with no offense to my dear new laptop) I still love curling up with my old fashioned laptop--my notebook and pen.
What have you learned this summer about writing that you didn't previously know?
