Becoming More Productive

It's hard when you have a lot of time, but I have to turn this around. I have to make this abundance of free time work for me. I need ideas to keep myself going throughout the day. I have e-mails to respond to, books to read, a body to work out, two yards to clean up and other domestic stuff to take care of. But, they don't seem to be the things that would make me feel productive. I have to learn something new. What is it though? I'm pumped, but I don't know what I'm pumped up for. All I know is I have to start becoming more productive. It's urgent.
