Analyzing the Delays after Making a Mistake

Do thank you, Jonathan, for your ispiring answer!

You not only answered on my question, but propose truly good advice! Indeed! 
You're right, I almost forgot that there are stuff that can be used to load the aoul!

First of all, about the anxiety - yes, I guess this is something very important for this case. Actually, I noticed that if I do exercises (musical or logical, or whatsoever), I usually never had any problems of such: after making few mistakes the speed (if I play guitar or typing texts, etc) was kept by the same level. While the later I start doing it (afternoun, evening, or night) the speed is sufficiently dropping down. So, if at night I make a little mistake the speed drop down very fast. So, I guess the anxiety is the best explanation.

Of course these are just my subjective introspections. 

Second, my father served in army, and at the same time he was a musician. He also played few bands - not popular. Mostly he played as a session musician. He played flute, saxophone, and drums. No doubt that the drums were my favourite instrument too, and even being a kid I tried to play drums. I had no intentions to a musician, and my father never made me play on any instrument, he wanted me to choice this deliberately. He said that his father (my grandfather) made my father to play some instruments, and he didn't want to repeat that mistake. But along with it he could swear that because my grandfather made him playing it helped him a lot, because it helped him become a professional musician. I'm not a professional; all I know was only by me. So, I had no interests in playing until ~15. Yes, I played drums, but it was just more fun, then serious. In 15 I started trying guitar, but my soul was not for the one, I liked bluesharp - the little harmonica - the one that some of old bluesmen had. I liked the idea that I could carry it whenever I go, and I liked that country western style. Time to time I visited a village where I helped my grandparents, and after doing some work I wanted to sit down near a bonfire and played something. But I must say to buy a harmonica wasn't so easy, because I lived in Kharkiv, not the capital of Ukraine, and those times (the beginning of 00's) such musical instruments as harmonica were not so widely popular. But after searching more stores I finally found one. It was a cheat model. So, there another problem raised in front of me - I had no instructions or notes, or whatever. I knew only one guy in Kharkiv who played harmonica, but neither me, nor my father didn't know him personally. That guy was blind (as Sonny Terry), and I doubted even if I knew him he could help me a lot. Anyway, later I found some literature. Year by year I found not only the literature offline, but as soon as I started surfing Internet I could find some info about how to play. Moreover, I was truly lucky when in one store a German/English CD-ROM about harmonica was selling. That was fantastic! Since that my technique started being more and more good, and in 2008-2010 I even played in few bands. Those bands were not professional, but I liked it. 

Yes, I also played guitar. Not so well, but I did it mostly by my own style, so I'd say I play in my own style. Even with a slider, or an electric. Mostly, acoustic. 

And I played drums also with few guys. I'm not a good drummer. When I needed the drums (the drum set) in my 16-17 my father didn't have them anymore. He often bought or sold them, so I didn't have them, and I couldn't allow myself to have them - must they the drums were usually expensive. But I played. 

Well, thank you again for your comments and question! Good luck to you!!! 
 

MAYA-EL

I did not smoke a thing at all between 2014 and 2020,
then the world went mad, so I had to alleviate reality a bit...

But I am shocked at how potent the ganja had become,
easily 10x stronger in some respects, maybe even 100x in other types of ganja.

I make a miniscule tooth-pick of about 4 small hits which i then rebreath in
a circular breathing technique similar to how you play a digeridoo,
so almost no smoke escapes, and that will bake me from breakfast to lunch.

If you are having negative effects, you just having too much.
When I restarted smoking, even half of one drag would be optimal for 4 hours.
That one spliff with 4 small hits is actually still too much for 1st timers,
these days.

In 10 years time they gonna make stuff so potent,
we gonna be levitating and walking on water after getting just one whiff of it.

Many regards! I've been waiting for such an answer! I wanted to underline that conscious moment in that delay.

Your addition sounds like the exact answer on this question. I still don't know how to check this new hypothesis. The anxiety Jonbain proposed is what can be measured more or less better. Let's say the strength of muscles looses or raises. However, the consciousness part allows to introduce even philosophical explanations as additional, which looks like a really interesting wander into the way to prove it.

Let's say that the process of thinking T about 1 thing requires 1 value of energy E, or it costs 1 unit of effort to waste from my total amount of energy E. So, increasing T makes E be raised straight proportionally, and as the result, the other processes loose their energy E from a total amount of it.

Here's another trap on this way – is to measure or to find out that total amount of energy. (What if it is being changed? Until it hasn't been measured, no precisely result is gained.)

I do like that you also pointed that tiny, but very notable point about the self-consciousness. Of yes, it looks like such a turning point may have occurred in such cases. Because instead of thinking of the current process, the attention turns into the depths of self-analysis.

If the self-analysis is the reason why the total speed drops down, then the self-analysis isn't good always. Maybe sometimes we just are tired of ourselves :) Maybe time to time it's okay to put someone else's shoes on?
