Aspirations

I want to be an animator. I've already contacted a school in Vancouver (Vancouver Film School) for information on their classical animation course. I must want it real bad if I'm willing to go away for a year to do the course....or even go away forever. Well...if I do become an animator, there are things that I have to give up. It is my dream and you have to let things go to accomplish your dreams. It pretty much sucks that I'll have to leave my friends, have to leave the comfort of home and venture into unknown territory, leave the safety of Newfoundland, my little island home. I want it. But...is what I want...really worth the things that I have to do to get it?
My brother usually makes this stupid joke about what he learned in his university physics course. He tells me almost every night, "Jessica, if you want to gain immortality...you have to kill a hundred babies." Of course we both just laugh it off....and then..I started to think about it. It some strange context..what he said was true (not in the way you're probably thinking). It's like this, if you want to be remembered, if you want to get what you truely desire, you have to do some things that might not agree with certain things in your life. In the way I'm thinking, "killing a hundred babies" could mean "leaving all the things that you worked so hard for in the first place" just to gain what you want. Now...there aren't people going around killing babies to gain immortality, but there are people that leave what they are accustom to to gain something they desire.
I'm not entirely sure if I want immortality enough to kill children. I really...really need help with this. I'm just contridicting myself when I think about the pros and cons of going away to get what I want. There's an equal amount of both. I'm horrible at decisions.
