Never fear a failure
Anyone can problem solve in a well stocked garage. It's time to be well prepared while in the wild. Bring more than the minimum, and be prepared for more than you expect. Breakdowns are a part of what makes life on the road interesting. With a fully stocked tool roll, they can be part of the story, rather than the end of the story. Get your wrenches out, and get back on the bike. Theres no need to call it quits when you've planned ahead.
