Similar to you I like to work on things which are very intricate. In the quietness of my home I really like to spend long hours thinking about it like you have mentioned on some hobby electronics or mathematical proofs.

Unfortunately most of the people in my social circle do not understand why I open a book or am at my computer again when I come home. It is very hard for them to understand that I really love to get lost in my own thoughts or at the very least daydream.
