Do you have a mantra or recurring thought that helps you get through the day? What is it?

It depends. Sometimes it's a matter of finding the next "milestone" and just looking towards that. Others it's an overall goal, like when I have vacation coming up. And, hell, some days it's just me chanting "You're not a fuckup" over and over again.
Being able to reach out and touch people on a regular basis (both literally and figuratively) goes a long way, too. Just knowing there are people listening and interested in me and what I'm doing. (One of the reasons I do ask.fm, actually!)
