Once upon a time

When I went to university I didn't have a driving licence, so I took the bus daily. Actually I took four buses every day: two, to go to university, and two more to come back home. It was a great time but the truth is that I looked forward to finishing my studies. I wanted to work and have my own money. It was really tough but I finally succeeded. A few months after I finished my degree I found my first job. By that time, I already had a car thus I could drive to the office. That was not such a great time as when I was a student. Although I like to see the positive point side: I learnt a lot of things and I won gained experience.
Going back in time, there's one thing I failed when I studied: I should have learnt English better. I admit it was my mistake. I didn't think it could be as useful as it is really. Now, I work and live abroad, out of my country and I'm learning a new language.
So, the only advice I can give you is you to learn as much as you can!!!
You never know when it can become could/might be useful. - It is very common to say, 'You never know when it might come in useful.'

Brilliant job, Antonio.  An excellent article, written with a very high standard of English.
