Ask HN: Do you have any active management advice for investing in public stocks?

Howdy!

I'm 27 and looking to dip my toes into the stock market game and I am looking for any books/tools/resources you have used that have helped to guide your investment strategy.

Ideally I am just looking for your opinion and any resources that give me a lay of the land of all the different types of ways that I can invest in a stock. It's just a whole new world to me and I desire to get introduced to all of the players!

Disclaimer: I definitely realize that active management is not always better than just investing in an index/mutual fund. However, there is no fun in that :). Plus, I am looking to try my hand at least once in my life so any advice you have would help me tremendously!
