I make one final request of all my students before we break for the summer: Write down your summer writing goals and send them to me.
When I have the entire workshops' goals, I email them to everyone in the group.
"Print this out," I suggest, "and post it by your computer."
And when we get together for our monthly summer sessions, we devote part of every meeting to going over each person's goals.
The act of writing down--and sharing--goals helps us achieve them.
If you're not in a writing workshop, find a writing friend to share goals with. Meet over the summer--online if not in person--and review your goals.
