Why am i doing Graphic Design??

Graphic Design. Why am i doing this course? Graphic design is one of the course that i plan to study.But it's not the main choice. Other than graphic design, my other choices are interior design and architecture. In malaysia, there are only a small amount of universities which offer interior design for degree.mostly are diploma certificates.     Then ,why didn't i choose architecture? My dad's friend who is an architecture gave me an advice not to study architecture because it's not suitable for females. This is not sex discrimination. Because he thinks that it would be a tough task for females as they have to burn midnight oil for the projects. Furthermore, to become an architect, have to spend at least 5 years of studies and add on another 2 years of experience,by then is a qualified architect. I choose graphic design because i have more interest in this course compared to others. Besides, i think graphic designer is a high demand career.
