Questions From a Novice Runner

As a beginner, I have some questions that are typical yet important questions I suspect a lot of fledglings wonder. So here are some that whirling around in my head while I run:

1. What is the right pace that pushes me but doesn't burn me out?
2. Whenever pain occurs, when is it good to push through or ease up?
3. How do I make sure I am setting realistic goals for running?
4. What is the right way to run hills, conserve or attack?
5. Why are there times I feel an energy surge later in a run?
6. How do I become a more focused runner so I don't get sidetrack by minor distractions?
7. How do I know when I am running too much in a week?
8. How long can I really do this running thing in my life?
9. Why do I now love running where I once barely tolerated it?
10. How much running stuff do I really need to improve my performance?
