One word that will fit me the most would be Passionate. I can do everything with passion, even with my studies. I make my goals everyday, and try to accomplish them before the day ends. I have long term and short term goals and I accomplished them with my passions. For example my hobby is to sing, I use my passion to make it my goals. It might sound confusing but it's who i am. It's what i do.
I believe that you need your passion in everything you do. Even though our purposes are not the same. Some might use passion to make another person smile. Some might use them to fulfill their own dreams. And some might even use them for bad reasons. But the bottom line is to use it wisely. Because once it is used, it's very hard to control. And at last a word that could describe a piece of your personalities would be passionate;)
