I'm sorry you are feeling this way. I understnad - I am very hard on myself when I do silly things. But I try to remember what my mom always said when I was growing up - everything happens for a reason. It seems taking the motorcycle class was not in the cards for you - maybe you would have hurt yourself then not be able to do your big trip. I"m thinking this was not the path your HP had planned for you today.
I'm still new on this site so I hope this is helpful. You have posted on a couple of my threads and I appreciate your wisdom and feedback.
