In spite of my age, I still do not know what major should I pursuit should pursue in college. because I have many passions and I like many diferent things. I also do not know where I will study because here we have a lot of good Universities where I live.
I like to understand the human emotions and behaviors .and I appreciate to see and help people to evolve as human being. I like helping. I like helping people. I enjoy seeing them evolve as human beings.
I also enjoy researching, discovering and creating.
I like organic chemistry, programming and quantum physics.
I would like to study philosophy too, but my family would kill me if I chose this area because it gives no money. does not pay well.
I would like to learn to play the violin, guitar, or piano.
I would also like to learn to sing and maybe form a band.
I like to write novels and poetry.
I love to draw and to paint on canvas, the smell of ink makes me smile.
I would really like to know how people choose their professions and get continue on with them for a lifetime. I never can't imagine myself doing the same thing the same way every day. That would make me find out what is boredom.  be monotonous and boring to me.
