Remembered another observation. This one's about bombs. Or rather, a certain thing connected to them. You know it. You hate it. You encounter it on a regular basis, no matter whether you're a vet or a rookie. You can say it with me now. Dying with bombs in stock.
Yes, that one. Unless you do a no-bomb run, wasting your limited resources like that is something that can easily frustrate you no matter what your goal is. There are only two kinds of players that don't encounter this situation as frequently as everyone else. One is master players who can execute their runs perfectly and know when to use all their bombs effectively. The other? Complete newbies. Why? Because bombing at the first sight of danger is among the first things they learn. But let's look at how it goes from there.
Suppose a newbie used all his bombs and is now against a not-so-trivial bullet pattern. Since all he can do is try to dodge it, he does try, and manages to luck out of it. A few lucky attempts like that, and he sees that it's possible to dodge stuff too. Next time, he sees a pattern like the one he managed to dodge before, and tries to dodge it instead of bombing. Sometimes luck runs out when you least want it to, and he dies without having used those bombs he still had.
Now, I think this is where a divergence between players happens. Some get too upset about unused resources, seeing that as a step back, and decide that it's impossible to get any better, and those who can NMNB Lunatic are just insane superhumans. Others, however, overcome their frustration after such failures and keep trying, eventually learning things and getting better.
Now, this "bombing skill" is a peculiar thing. When you start getting better overall, it drops, but you can relearn it as you get better. It's like when you try to learn martial arts or playing an instrument. You can do it untrained, but when you start training, you can't help but think about what you're doing, and can't do things as easy as before. However, with time, you learn basics to the level when you don't need to think about them constantly, and are instead learning more advanced stuff to make your performance even better than ever before. This initial drop turns away many, but it's inevitable, and once you're past it, things are only uphill from there.
So, about dying with bombs in stock? It happens. It's frustrating. But learning to get over that frustration is as important as learning patterns or techniques. Even kappas get swept away in the current. Even masters can make stupid mistakes. But it's not always required to have an absolutely perfect result (except no-miss runs, of course). That stage 1 stupid death you could have bombed through? It doesn't mean you won't get a 1cc this time, or that your further performance will be exceptionally bad. Unless you convince yourself that it would by getting upset at a single mistake. Keep fighting, friends. There is no such thing as a wasted run if you're having fun.
(Man, where I started and where I finished. I shouldn't write so much or I'll be losing my train of thought each time.)
