I can understand exactly what you've written, but there are a few small errors I'll fix for you. I've also added a couple of words that I think make your meaning a little clearer.
During my work in a hospital pharmacy I have learned many things. One of the most important things is that proper organization saves time, effort and money.
We can learn how to organize from our own work experience, but it is faster and more effective for us to learn it in an academic way.
I hope to continue my work in health care management and organization in fields like hospitals or the pharmaceutical industry. So I have found this course to be a good opportunity to take my first steps towards achieving this dream.
