How can I be successful in the future and reach my goals?

Just to give you all a little background info on me. I am 17 years old and in 3 weeks I will be starting grade 12 and I am very excited but also very nervious since I will be attending a new school and I know no one there… yet.
Anyway I am taking a business course for 4 years or however long it will take me to finish.

Then my goal is to move to Spain or Italy… maybe the US or Canada but mainly Spain because I am just in love with that country. Ever since I heard the language and saw the food, the boys, everything I just fell in love with it. Now I have been studying Spanish for 1 year and I will continue until I finish school, and I regret not starting earlier.
Thats my main goal in life, move to Spain or italy, have my own online store, open a beauty salon for women of colour because most of the times we are always left out or own a clothing store in Zambia with imported items from all over the world and also work with some charities in Zambia or even start my own.

Obviously to reach my goals I need to study hard and do my best in school. But other than that what else do you think can help me make it? I wanna have a bright future :P
Its not all about money for me, its about doing something for others and enjoying life because its too short to be worrying about other things.
