Postgraduate course

I think is important to do and study everything that you like and evertything that is possible, specially becouse this would make you happy and also you would have more possibilities for a good job. I would like to complement my studies, but I'm not sure yet  about what to do, becouse I like many things.
Something that like me very much now and maybe in the future is to work is in a Tourism Agency, beeing obviously a tour guide. I would like to make people know about the old buildings and their stories, who lived there and what they made. When I have been gone to tours, I think is great to know about fun facts and maybe some things that nobody else know. But, something that slows me down, is that I'm shy to speak in front of many people, and probably I will forget everything about the place. Anyway, If I really want this I will have to face it.
Other thing that maybe I will like to do is something related with Theory of the Arts, I don't know if a magister, a diplomat or what, but the history of the Arts like me very much and I would like to keep on learning about this.
For now, I'm concentrated in this carrer, but when I finish it I will search about places to study, and I hope to have a decision about what too. For the being time I just know that this will be a physical place, becouse I don't like thinks online, maybe it can be part-time, meantime I will be working on my personal projects.
