First of all, excellent and thorough introduction. I'm impressed by how well you articulate yourself, but perhaps even more by how early you've discovered how to achieve what you want achieve, and how to do it. This is rare in a teenager, but you probably know that.

I like this quote:

I want you to realize that if you start taking action TODAY, and start working your ass off

Here's some words of wisdom from the far east, with a similar message:

The best time to plant a tree was 20 years ago.
The second best time to plant a tree is right now.
-- Chinese proverb

I share multiple of your stated goals in my own life, where helping people is probably the most important one to me (besides helping myself of course -- how can I help others if I'm not able to help myself). I've also had a big interest in self-development since my late teens (I'm now 30), and also have quite the large number of hours consuming various content of this type (most recently, the talks of Jordan Peterson -- if you haven't checked him out yet, you won't regret it if you do. He's considered one of the most influential intellectuals in the us and canada these days)

Given your apparent razor sharp focus in life, I want to tip you off about an educational program that actually takes place in Finland as well. I've almost completed the programme myself, and let me tell you, it's unlike anything you will find anywhere. It's a new type of education (not just a new education): An interdiscpiplinary meta-dicipline. It has been around for almost 40 years, but they don't do any advertisement whatsoever, so the only way to stumble upon it is by recommendation. I'm convinced you will get a ton out of it if you do decide to check it out. You can read about it here, and here's the program.

Good luck with everything! I will be following your blog with interest.

Last note: Of course pineapple is delicious on pizza. Doesn't everybody enjoy that? :D
