That's actually in incredibly good, rational method for learning to write. It allows the writer to study an existing model, practice, then compare against the model afterwards. One could do this with pretty much any author, journal, or paper that you enjoy, and it should be effective no matter the type of writing.
Now that I think about it, I'm going to suggest it to some friends of mine who teach English classes in the area. Thanks!
I think you're on the right track, Caesium. I've arrived at 41 years with a dynamic 25-year plan ahead of me, and I would suggest that you spend some time spreading yourself among very different activities and causes for at least four years, then consolidate your time into what you enjoy most. You will find that not all charitable organizations are equal, and there will be some causes (whether charitable or not) that really grab you by the short hairs and demand your attention.
Think of it rather like the second run at your school life - you start with as wide a net as possible, gradually close in on what you're good at or you enjoy, then focus on what works best for you. The benefit of your schooling will allow you the luxury of choosing your path in life, but make certain that you've at least taken a peek down the others before you go too far.
Lastly, I believe the desire to make money for the purpose of donating it is fairly recent. The Bill and Melinda Gates foundation was created at Melinda's behest well after Bill had achieved more wealth than any nerd imagined. I'm definitely not knocking it, as I myself donate to PBS and am on the board of several charitable organizations. The goal of making money to donate money is a trend that I believe speaks very well of the future of humanity as a whole.
The world is not an inherently kind nor fair place. It is up to us to make it so.
Human nature dictates that we both assume 'someone else' is going to start a group, and assume the task of creating said group is very difficult. So even those people who lurk and say to themselves, "Gosh, I'd love to have a group like that in my city" won't take the first step unless they are given "permission".
In that sentence, you really did hit the nail on the head there, Bentarm.
