Why I have chosen psychology?

I think one of the most important question after your graduation at school is : what are you going to do in your future?
This question is really hard and it's not so easy to find the right answer. All my years in school I was thinking about my future and trying to decide what job I would like to have.
I think it's quite difficult to know what you really want from your life when you are only eighteen years old. When the last moment came and I had to fill the paper of my application to university I was very lost in all my minds and wishes. So I wrote about ten specialitys and was waiting for the answer. So firstly I was accepted to Vilnius Gediminas Technical university, environmental engineering. I was really upset of this fact and it wasn't pleasure for me to learn such subject. All the year I was thinking about my future and trying to imagine what I am going to do with this speciality. It was quite boring to learn this subject, so I decided that I have to make a decision and change something.
I read all speciality's programs and try to find the most interesting for me. After long thinking I decided that psychology studies is the most suitable for me. I think that this subject is very broad and could be useful in many areas of life. Cause understanding other people is one of the most interesting and difficult task.
