Balancing yourself between family and everything else you have going on in your life is a tough subject to tackle. Your family is one of the most important things you have to balance in your mental compartment of prioritized necessities. The members of your family are something you cannot choose; they are something you are born into. Every single person you share a blood relation to will be important in your life whether you want them to or not. It is extremely hard growing up and everything that comes with that. You become your own person and you especially know what makes you who you are before you become the adult that you define yourself as.
Being in college classes is one case where you especially distance yourself from your family members. You become a new person, you start to understand the difference between high school adolescent version of you, and the newly discovered, knowledgeable version of yourself. Becoming your own person is a scary process, but it is a part of life that you cannot escape. You become independent; you learn what makes you important. You learn anything and everything that makes you an individual in this big bad world.
Anything you want to accomplish in this world is achievable, no matter who you are, no matter who you are trying to become. Anyone should have the freedom to explore the options they want to experience, no matter what background they come from. School, work, friends, hobbies, everything that is keeping you from being who you are is nothing but an obstacle in your way that you can easily overcome. You have to realize that out there in this huge world full of variety, there is an endless possibility of what you can and cannot become. The world is your oyster, as stupid as that sounds.
