Has it happened to you that you can't concentrate and you're so in your mind that the "outside world" seems 2 b too far?
Let me tell you how I came up with this question, so that you understand what I mean:
I study 2 careers and i'm the owner of 2 businesses, so my mind is always working in numbers, taxes, debts, customers, school, family, etc. In a way, I'm used to live like that. However, yesterday it was different. I had to do 3 exams yesterday, as well as finish 2 final projects, also had to get the money to pay some debts and to keep up with an ongoing investment, I also had to meet with a customer, and on top of that, I had to do a projection because I'm gonna pay the hospital for my sister who's having a baby next week... So, is it normal that my mind was "unavailable" when doing one of the exams? My reasoning ability was totally gone. What do you people think?
