It's all about making the most of your time, so have a "GIT ER DONE" attitude while you have the few minutes in the day for yourself.
***REMEMBER-these are my times and speeds, you need to work at your own pace. I built up to this-if you can't sprint for 90 seconds, then don't. Try as hard as you can, sprint and jog at your own pace. Push yourself, but don't injure yourself.
I always like to make little bets with myself. I promised I wouldn't stop until I got to 2.5 miles and I wanted to do it under a certain time. So I proved to myself that I could do it and the pay off was sweet:)
