I still remember sitting in class and making the computer print "Hello World!" for the first time, I was in shock. I didn't think telling a computer what to do was possible as a kid, it felt like magic.
After years of practice and constantly asking Google questions that usually start with "how to...", I asked myself "Why do I love this so much?" and the answer was: because it's a way for me to combine logic and creativity - the two things I enjoy the most.
There is certainly more to learn, explore and build, and that is what makes it exciting to me.
