As A Teenager, How Can I Make Money Online?

I am a Nigerian girl in a family that is financially in need of help. I am the first born out of five kids. I am fifteen years old but I am logically mature. I want to assist my parents in catering for some of the expenses.
I do not want to hawk items on streets. I will never oblige to being a sales girl or a house help like most girls around here do.
No, I want something that is prestigious and helps me to showcase the power of my intellectual facility.
It is not by my strength that I will find favor in the sight of all those who wish to offer me scholarship or any sort of sponsorships during my journey to success and financial freedom, but by God’s grace.
I guess I have been preparing for a long time as stated in my eBook that “the will to win is as important as the will to prepare.”
I have read many blog posts and online articles (thanks to my old model mobile phone). I’ve saved many web pages as offline pages in my phone browser so I can go over them later. As someone once said that to be a serious writer “the more you read, the more you write”.
I have written lots of notes on countless number of topics that bug me. My notes are mostly from the internet, TV/radio interviews or talk shows, in fact anything that inspires and motivates me to want to get more out of life will get written in my notebooks.
I know that I don’t have much money to start up a business (as I want to be self-employed). But after taking a deep look into the internet, I realized that there are many highly-lucrative businesses I can set up with just my hobbies and pastime.
I have my dad’s laptop all to myself (though all the software/applications on it are of older versions). I have a broadband modem which connects me to the internet and so every other thing could be gotten along the way.
And so here are the online businesses I will set up (thanks to the internet);
1) Blogging: - Have my very own online magazine and publish articles and posts that would inspire and lead many youths on the path to success.
