never say it is too late to learn everything in this world (Please correct about my writing)

I made a mistake in the past. I went to colledge with the major that I was not interested in. Agriculture was not my interest. I am interested in medical sciences and foreign language.
I made many considerations when I had to choose the major. The main obstacle is funding. I was accepted at two public universities, medical science (dentist) and agricultural. I choose agricultural university because the funding is (/the fees are) more cheaper. It's difficult to learn something that you were not interested in. But all have passed.

In this stage (/Nowadays), I realized that I am very interested in foreign language. I think it's not too late to start learning about foreign language. So, I start from now, even though I learn through the internet line, I enjoy it.
