You can do it!
All of that internal noise in your head is your anxiety over the things that you have yet to experience. Omne Ignotem Pro Magnifico!
Buddy up and get with a local Triumph rider and spend some quality time to know your own ride... because there is no other like it! Perfection is an illusion, so don't try so hard to get everything just right. We learn when we make mistakes and the outcome is usually not as bad as we make it out to be beforehand. Besides, these bikes are very forgiving. Ride on!
