I don't have enough tunnel vision when I try to call for it.
Then again, too much of it comes up without a warning.
Few days ago I decided to after a certain design goal for one system I'm designing. It's gonna be a presentation of skills for my education, I'm not sure if there's an english word for it. I spent 15 hours finding the perfect piece of hardware for it, even though it would have costed a maximum of 100-300$.
Idiocy sometimes hits the determined person.
