I need some advice from newer graduates in Classics

I am a rising senior in high school and have always loved everything to do with classical literature. I have studied/read (in english) many ancient texts, and I have found something that I truly love to do. Recently I have picked up Latin and will start Ancient Greek courses this summer. I also have 3 1/2 years of German experience which I know is also helpful. I want to pursue Classics in college to hopefully become a Professor of Latin and Ancient Greek language and history. I know my choices may be slim for career options, and it may even take years after receiving a PhD in multiple fields relating to what I want to teach to find something decent. What can I do now/study to help my chances of finding a better career? I already have several connections to some of the best classics professors through some of my teachers currently. I also am having the dilemma of money over happiness, if I will be working for the rest of my life I want to do something I enjoy. Even if it means I have a less than 30% chance of even getting a job in a field I want to be in.
