Ride when you feel confident. There are certainly days where people are off, whether it be from their mind being else where or other situations. It doesn't help you recognize your surroundings and help protect yourself if you aren't riding with your mind in it. I would just tell your mom it is something you want to do and if she can't give positive feed back towards your enjoyments then her comments are not welcome, and she is better off keeping them to her self.
