Because i will i need in the near future, 
Depend on my diplome i need the chinese lang beside it that will increase my CV.

I tried to learn chinese and i think its difficult to learn it for a few days caused i keep on forgeting the words. 

I have learned Mandarin by myself for five months and just started speaking lesson with an Italki teacher for one month. I kicked off a personal project called "Language and Travel" to build one of my hobbies and Mandarin is the first module in the project. Spanish will be the next that I was planning to start in this August. I can understand a little Korean which I learned 9 years ago but haven't practiced for a long time. I planned to review it soon after Spanish. It is really interesting.

How about you? What is your purpose to go with languges?
