There's never a good time to get injured. It's always a hassle and it always throws off your life. But it doesn't have to stop, not even your fitness. You won't be injured forever so if you can get through it without stopping all the way, you'll be fine.
No one likes to be told No, even when it comes from yourself. That defiant child in you says, "I can if I want!" Yet that defiance is getting in the way of your health, your body, and your peace of mind.
