I was riding my single speed bike to work. I came across a steep incline, so I pedaled harder. The chain snapped. In hindsight, I should have carried a repair kit with me. I used the Fred Flintstone method to get me the rest of the way, and I still made it to work on time.
I showed the broken chain to my coworkers. "Anybody know of a bike shop downhill from here?" Nobody laughed. One guy asked if I had anyone I can call.
Sure, I got people I can call, but I decided I should take a crack at fixing the chain. It turns out that a pin popped out of a bushing, and two outer links were bent out of shape. I was able to fix these with pliers I bought at the gas station. I was able to make it home as long as I took it easy and didn't put too much stress on the chain. I still need to buy a new one, though.
Now there is nothing wrong with asking for help when you need it. I've helped others when they needed help, and other people have helped me many times. But try to avoid needing that help in the first place.
Self-reliance. Pass it on.
