Investing 101

[Fortitude]

I'm a 20 year old Canadian just starting out in the investment world. My income is in the neighborhood of 200k / year (hopefully more, we'll see how the year goes) and less than 50% of this is used for expenses. I don't have any financial responsiblities to worry about now or in the near future - I think this means I am eligible for high risk investments.

I'd like to start by putting 1-2k / month into an investment of my choosing and gradually increase that amount as I gain more knowledge and my income increases. Taking into consideration both my limited knowledge of investing and my current care-free situation, what are my best options?
