Looks like my goal to bike each day to work this month is going to succeed. One and a half more days to go. The first 2 weeks it took some perseverance, but the rest of the month it would have taken a LOT for me to want to take the bus instead. This morning I got on my bike after a long weekend (I had Friday off) and within a 1/4 block I had a smile on my face and a happy feeling in my chest. What a pleasant ride in this morning. So much so that I was even feeling happy to get to work on a Monday morning. :)
Congratulations on making it a full month!
On Friday I took my road bike back out a gain, and had the same problem happen while climbing a 17% hill, but this time I know the culprit. Recently I had added some links back to my chain because I think I took too many off. I guess the action of doing that so many times caused one of the link's pins to become loose. The loose pin had worked itself out a ways, pushing itself against one side of the cage, and the link this time got split on the other side, causing the jam. Luckily I happen to carry a multitool which includes a chain link tool. So I got to the side of the road, pulled off the now bent link, and got the chain put back together. I've ridden 70 miles since and no trouble.
The best feelings have come recently in the midst of adversity, where I had bike trouble and instead of getting discouraged, figured out how to fix it. Flats used to be discouraging, now they are just a temporary delay. I also was having noise in my bottom bracket on my commuter. I washed both bikes this weekend, and was looking into what could be the problem. I took apart the bottom bracket, and when I got to one bolt which holds the left crank arm on I noticed it was extremely loose. This is the one which is responsible for keeping the two arms together. After cleaning everything, greasing things that should be greased, and putting it back together I now have no noise. Didn't even need a Youtube video this time.
