To start a self-presentation by telling that it's hard to do a self presentation maybe is a bit like starting a speech by saying "I'm not a speaker", on the other hand, its true. It is hard. It's the people around you who know you the best, and even they will have different opinions depending on their own preferences and what part of you they've seen. A human person is a complex thing with lots of parts and bottoms and not easily seen and even more uneasily described. So I guess no presentation of you will be fair, specially not those written by yourself. You need to explore a person yourself and make up your own opinion...
Anyhow, here is a short version that I wrote before I wrote the babble above..
Likes music and mathematics and in general any kind of art. Tries to play some instruments, writes songs sometimes and likes photographing. Likes being in the nature as well as obscure cellar clubs. Spends a lot of time thinking of spiritual and existential matters.. Not very good in making contact... I'm quite introvert I think.. on the other hand.. very extrovert.. hmm.. not sure..
I'm a person with more questions than answers.. so if your looking for someone to give you all the answers about how things are, I'm not the one.. the world is an open place..
