Help Please!

I started running a few years ago and absolutely love it. I learned so much about running, form and nutrition through the challenges I gave myself... 2011km in 2011, half marathons and also a full marathon. However due to a ITB injury followed by several surgeries I've been out of action for so long that I feel like I've forgotten everything I learned.

I have a wonderful place to run and the winter weather here is perfect but I need advice, motivation and kind words about not being mean to myself for losing speed and stamina!

What's your favorite advice you give to your fellow runners when they're getting back into running after a break? What's your favorite running mantra? Please share with me and help me get back out there without giving myself a hard time!!
