In life we need to be wise on deciding something in order to have a good life in our future. But sometimes, it's not that easy to decide on something as many think it is. It takes time to mold and build up your own opinion, others opinion, and what you want on your own vs. what others wants best for you. It takes a lot of time to decide. But the hardest decision you've ever made in your life is choosing between things that aren't right but it makes you happy or doing good things that aren't even make you happy but others do. It was just like choosing your own track and journey on college. 
It's choosing between what you really want and what your parents want you to be in your future. 
You want to choose your happiness 'cause you know that you'll surely excel on that field. But on the other hand, you don't want to disappoint those special people that surrounds you who thinks that they really know what's best for you. 

Life is full of logic. You need to feel pain and broken inside for so many times for you to become stronger to cope up your future challenges in life on your own.

Just always listen to your heart. Know what you really want and know some things that you really love to do that makes you happy. And lastly, don't ever doubt yourself, be brave enough instead. 
Sometimes, it's not that bad to disappoint our loved ones by disobeying them. But make sure that you'll succeed in the future. For them to realize that they're such a good family to you for not being so self-centered and for sure they'll be proud of you.
