Adapt to the scope of the university!
When we started we did not even know the career that we really love, but it is a process of adaptation and we all went through it, it has to be since this is what characterizes us in the future, as professionals, it is not easy but it is not give up!!
Many also think it's fun to go to college just for fun, but if you do not study you think you'll be successful? Here is the mistake of many, of course it is not a lie that you will have fun too, but not everything is entertainments.
Just tell them that perseverance is the way to success, you will cry, you will scream, you will have fun, you will enjoy your friends, but if you are perseverant you will have your reward at the end of everything, which is what we all want, well the majority is to obtain that title that defines you as a professional, that characterizes you that the studies make you great, both professionally and personally.
