Reminders

-Run regularly
-Don't think how long the run is first thing after waking up, etc; focus on putting on the running clothes, then having breakfast, then brushing teeth, etc. Then go!
-Take it easy if that's what you need to do. Jog if can't run, walk if you can't jog, etc.
-Don't push and push just because you got that runner's high. Just run the set amount that you had set out to do, rest, recover, and reserve your energy for the next run.
-Pick one "limit" (a set distance, a set time, a set speed, etc.) and stick to it, whatever it takes. Congratulate yourself for meeting that goal regardless of how long it took you/how far you got/etc.
