Things you love to do vs things you're suppose to do

We we're chatting away in class the whole day today since most of the teachers were busy with this photography session and so, we've came to talk about plans after SPM. A friend of my totally had no interest in pursuing science-related career but of course, she knew where her interest lies and what she really wanted to be. As for me, I do have some clue but it's always uncertain. I do have things I really love to do and one of it is music. At one point of my life I really wanted to pursue in music but unfortunately, my parent's aren't supportive enough of this and practically "thinks" that I'm not meant for it. I wasn't really upset about it because I do understand the situation we're in. Studying music is not cheap and I can't guarantee if I really can do it. Of course, most of them say, when there's a will, there's a way. Yes, it's true but I just can't gamble my future with it. Plus, I have a younger sibling, well at least if I didn't get to do what I really like, I do hope in my place, she gets to do what she really wanted to do. Lucky thing I'm born flexible like a vulcanised rubber! So far my best science subjects were Physics and Chemistry. Chemistry was my best last year but it seems like Physics has overtook Chemistry's place. There are some goals in life I've made. Seems big to you but I would really like to make a change in society. Therefore, in no matter what career you choose you'll learn in the process and sometimes, it's not necessary to pursue what you really like because the passion you had in you, can still be forever growing no matter what. There's a fine line between the things you love to do or enjoy doing which I generally classify it as "hobby" and career. All career can turned out to be your hobby at all times but not all hobby can be make into a career. Of course you can, under some circumstances. I've been helped a lot in life and me too would like to be like them one day. I think it's very generous for someone to share knowledge with you and worry on your behalves. Work  hard and smart in life and endure all odds in life. God is always there and will always be by your side. When the going gets tough, the tough gets going. There's no smooth sail in life and there are bound to have bumps and cracks in life. This moment you're enjoying and suddenly in split second, your world might be tearing apart but it's okay. Why? I don't know, you think. HAHAHA
