will let everyone else address the motivation side
In regards to falling and hurting your self, it will happen eventually but then again the ISS might fall out of the sky and hit you
. (point of interest the ISS is always falling out of the sky ......)
There is little point to being worried about it, aware of it yes but not worried. If you are riding with other people then you know someone will help you . In my last accident I didn't want to call family as they where all busy so I walked 4 miles to the hospital..... DON'T DO THIS
Let us know how it goes, and wear a helmet
