Need direction to continue learning

So I am 20 years old, a rising Junior in college, and am very interested in a future in Asset Management or even a hedge fund down the road. I have read some of the widely recommended books such as The Intelligent Investor (which was somewhat confusing), Margin of Safety, and The Little Book That Beats the Market, among others. Although these books are have taught me the principles behind value investing and some simple formulas for finding undervalued stocks, I am having trouble taking it to the next level. What I mean is I if I were to analyze stocks on my own, looking at financial statements and trying to come up with a value for an asset, I would be stuck. I have tried to read some books such as Accounting for Value by Stephen Penman, How to Read a Financial Statement by John Tracy, and some of Damordaran's valuation books, and all of these readings have been too complicated for me to understand. Could someone recommend me some very introductory readings on these topics? Also, I would be interested to hear how investors that invest their own money got to the point where they felt comfortable being able to do it on their own (ie. what they read, internship experience, things along those lines..) Thanks in advance!
