Are you convinced that you should be saving some of your money to donate later? Not sure where to start saving, what to invest in, or how to take advantage of tax benefits? This blog post is for you.

Note that this is a risky allocation, especially with margin. There is a solid possibility that my portfolio drops by 70+% at one point or another. You should make sure you understand the risks of using margin before following this strategy: you could end up losing everything, or even owing money to your lender.
For full details and reasoning, please visit the blog post on my website. I go through different ways to access margin, asset allocation, taxes, and different types of accounts. I look forward to discussing in the comments.
