It kind of depends for me. Usually, it's having other people work with me to a common goal that motivates me. Without my fellow Education peeps, I never would have been able to handle the Education program at college. We kept striving hard together to succeed and helping each other with ideas and such. I tended to write poetry about our situation to share with my friends because it helped motivate them and it was somewhat a coping mechanism for me.

When it comes to exercise, it's always helpful to have other people doing it with me. I used to go running with my roommates every once in a while to help build the habit. I did do a lot of running by myself too as it became something I'd do to get out of the room, think about my problems, and listen to good music/a literary theory podcast. Running with others helped start the habit and made it more enjoyable, though.

With writing, I need to feel like I have people that will read my stuff. That's why the writing prompt thing is nice for me. We can all share our things and strive to improve our writing. When I feel like I don't have anyone to read my stuff or brainstorm with, the amount of writing I do seems to take a nosedive.
