"If I have seen further it is by standing on ye sholders of giants."
- Isaac Newton
There is no point in being born later if you aren't willing to use the tutorials and cheat sheets earlier generations have created.
You don't need to re-invent everything from scratch. You are not proven less intelligent than your predecessors by skipping to the end of the book (that they wrote) and reading the answers. Rather, doing so gives you more time to work on the next hard problem.
