I wouldn't say admire. When I stumble upon code from many years ago I (somewhat painfully) realize I've lost a lot of the ingenuity I used in my early days. I read the code and find myself thinking "how the hell did I come up with that solution". I didn't care about finding the optimal algo/ds, I would just use whatever I knew at that moment without a second thought. Now I have to care a lot more about writing code that looks smart and learning "new" frameworks.
