    While I'm coding, I frequently take side-trips into framework/dependency method sources to make sure I really understand what's going on (as old Smalltalkers do). This helps me catch a lot I'd otherwise miss, but sometimes it can be a problem when pairing.

    But what if I have objections? I’ve been practicing a new decision strategy. If there is no way a decision doesn’t make sense, then I’m just going to make it and deal with the objections later. This has relieved a load of stress for me.

    If we’re using technology X poorly and are frustrated, then moving to Y won’t help. We won’t experience frustration for a while, but only because we are distracted. All the same dysfunctions will reappear. Instead, start working better and then re-evaluate the technology.

    1/3 It occurs to me that it might be fruitful to look, not at what Agile is, but what it isn't. If there are orgs that are not Agile (I believe there are), what characteristics prevent them from being Agile?

    “Just think how much more productive we would be if we *weren’t* having fun!” Nobody says this but they certainly act like it.

    My code can’t be tidier than my thinking. The purpose of my tidying is to clarify my thinking by manipulating the code. The code ends up better, but because I understand more not because I somehow forced it to be better in spite of my confusion.

    Delay is a precious, limited resource. It only seems the supply is infinite. Don’t waste delay on reversible decisions.

    Given a behavior-changing diff and a subsequent structure-changing diff, can you derive the behavior-changing diff as it would have looked after the structure change? Can you compare the actual diff with the derived diff?
