What do you wish you had more time to do?
With exception to eating, sleeping, or perhaps doing stuff with my wife that married couples do, there's nothing I'd rather be doing than immersing myself in a good book or writing to my heart's content.
For me, reading and writing go hand in hand. I not only read to learn new things, but to study how the authors frame their arguments, with special consideration to their style and word usage. If I come across an unfamiliar word, I immediately look up its definition. These strategies, in turn, help me become a better and faster writer. I've also observed that the more I read, the faster I become at reading.
Unfortunately, reading, writing, or indulging in any other hobby all day long just isn't feasible. We have all those other things to tend to -- you know, work, doing groceries, washing clothes?
No matter what, I make every effort to carve out at least an hour each day for reading and another for writing. When time allows, I can easily spend three or more hours reading on a given day.
