The brain is something so complex that in some situations I find it hard to control my own brain.
It's like this, today the enthusiasm of programming caught me again so I decided to read about some miscellaneous things here and there. The problem is, throughout my reading I encountered several links\pieces of information that sparked my interest. And from those links I saw other links\pieces of information etc... ending up with a ton of tabs opened.
I even ended up installing a combined scripting-programming-batch language(something like an advanced BASIC), "AutoIT"(I focus on C++ though, but for fast funny things this is awesome). With this piece of shit, if you have da' skillz, you can create complicated software in hours !(ok this sounds ridiculous).
I also read that it's possible to have lucid dreams. It says that's a cool out of the body experience, creating your own universe. I always wanted to fly... I even had a cool dream where the sensation was almost real...But it's hard. You have to keep a dream journal and practice everyday "reality checkup" so that it goes somewhere inside your brain so that you can "remember" to do this in a dream. It's a somewhat progressive evolution, and at its peak is where the fun starts.

tldr: I wish I could control my "flow of interest" or something like that, so I can concentrate on one subject at a time.
