You should study English!!!
Everyone should study English because is a one of the main language on the world. My advice is that you should effort yourself to learn vocabulary and when you have the possibility to practice it with other person, you will have to do it, so you are going to improve quickly your English. Several companies in Colombia and other countries require that your staff speak English well, so when they are going to hire staff, the applicants have to have an excellent English level. Whatever career that you´re studying should get together with English language because in a future it’s going to be very important to get a good job.
