In addition to sleep (I would get SOOOO much sleep you guys) as everyone else said, also use it for additional free time
Play video games
As well as sleeping though, I'd probably do a ton of research and maybe refine a few new hobbies.
Besides the obvious pantsing your friends for the Lolz, I would most likely use it for little things like fixing the house, or helping me stay on time for things. Never have to wait for a train to go bye while going to work making me late ever again.
To be honest? Sleep. I'd use that time to sleep and then be able to present a full 24 hours a day and be way way way more efficient.
Alternatively? Pull off stupid tricks.
I feel cheated. I saw Jinx's quote pyramid going down to Formalhaut and Freya, and so hit click to show to see what pearl of wisdom everyone was quoting. And it's my own bloody post. I wanted new and original content, not my own inane nonsense!
What if you had a massive heart attack while time was stopped and couldn't snap time back? Would people come back to find you suddenly dead? Would time come back at all?

I would use it pretty much exclusively to smurf with people.
And, of course, to kill.
Whenever someone is about to eat a peanut I would stop time and flick the peanut. Flick it the hell away!
Whenever I see unorganized queues, I would stop time and rearrange the queue in the order I see fit, based on what I perceive their karma to be.
I would use a hair straightener on jon snow's hair. I wonder what he'd look like with a Rihanna bob.
I would place pigeons on people's shoulders.
...and french fries in their hair!
But in all honesty, I would probably do a whole lot of trespassing. I love abandoned buildings and projects, but I'm too much of a wimpy accountant to have the guts to go explore them.
Every moustache I saw would mysteriously become a Hitler moustache.
I would read and play video games. Then I would unfreeze my kids and make them stay their cute young selves until I was finally ready for them to get older.

Whenever I see someone about to use their computer, I'd stop time and sabotage their computer by pressing the Insert key.
