Since I was a child I loved to learn. Later on, when I was at university I discovered books as an amazing way to learn. A good computer book brings a smile to my face and there is nothing better than reading a book and realizing "Wow! I get it now! I thought it was so difficult, but now I get it!".
If I was able to bring this kind of joy to a few passionate geeks out there it would be all worth while!
