I've been thinking about my performance at various tasks and where my focus is at during them and something's really got me confused.
It makes sense that devoting all my focus to a task while I'm doing it would yield the best results that I'm capable of. In my case, however, the opposite seems true.
If I'm trying my best to accomplish something and it's not working to my satisfaction (bugs in my program code that don't appear to have a reasonable cause for example) - and this only happens when I'm really focusing on the task - I get irritated with my apparent inability to come to the desired result and my performance declines, which irritates me more.
On the other hand, if I have my focus split (i.e. playing a movie or tv series while I'm busy with the task), I stay a lot calmer and generally my performance at said task stays pretty high.
It's very clear to me that I don't perform well under pressure, but in a lot of cases, there's no pressure aside from what I put on myself.
So my question is this: how is it that when I'm just absent-mindedly doing something, it generally turns out better than it would if I focused on it and tried my hardest?
