Motivational letter (help needed)

I am a high-school pass-out and want to pursue a career in Hotel Management. The university i want to get into is Hotelschool The Hague in Netherlands. In their online application form, they are asking for a motivational letter (about less than 2 A4 size sheets). I managed to write about 190 words which is way too short. I need some help regarding that, on how to increase the number of words which might impress the college's addmission administration.

Thank you soo much!

the letter i wrote is as follows:

Statement of Purpose

My interest in the management field had me looking for courses that will help me gather knowledge and also garner my skills. The course that your university, Hotelschool- The Hague, is offering, i.e. BBA in Hotel Management fits my understandings for my future. After graduating from your university I wish to see myself as a qualified and a proficient individual in the hospitality industry. The small-scale, in terms of the student teacher ratio, of your institution is the major reason why I wish to study there. Not only does it ensures more personalized interactions among the student teacher fraternity, but also ensures. Better quality of education. In Hotelschool- The Hague I wish to hone my social skills and my practical skills regarding all aspects of hospitality management.

I come off as a highly motivated and hardworking individual. I have recently completed high school (results awaited). Seeking an apprenticeship in the Hospitality industry to build upon a keen interest in management. Eventual career goal is to become a fully qualified and experienced individual in the hospitality industry, with the long-term aspiration of starting up own chain of restaurants.

Please guide me.
