Fomr the very first day I got my bike I was taught to practice something every time I was out. Emergency breaking, scanning, ooking through corners. Anything, just practice something. I have also tried to instill this theory in my wifes riding and my friends riding too. On a 15 minute ride to work you can work on a skill you have not had to use in quite a while (switching fron on to reserve while riding as an example) that will save you a lot of headache.
