I think first thing that I should sat -- I'm programmer. So that means mathematical education, logic-centric mind, boring intellectual talks and all of these stereotypes. To some extent it's true. But I also extremely love my creative beginning and spend a lot of time with less tech things. Also I'm sure that tech work can be a really creative activity (mine is just such). However, in last few years I'm not only a programmer, but also some kind of team-leader, so I know about such irrational things as human relations.
Speaking of life principles, I really try to be a "good man". That might be boring too ;-) from some points of view. But it also has some positive sides, such as politeness and attention to other people.
During the last couple of years I have seriously devoted a lot of effort to the health of my body and mind. For example, I quit alcohol and all other types of mind haziness. And I do a lot for regular yoga practice.
And I also spend a lot of time on self-analysis and fixing my own shortcomings.
