Probably that was the time when we were academic, not professionals.
Probably we worked at our own pace back then, not bound by a constant delivery responsibility.
Probably we were more curious and less competitive.
Or probably there were lesser number things to focus on.
The joy certainly lost its intensity to say the least.
Where do I find joy today ? Working on things which I find not only challenging, but also important to solve. But I also realize now that whatever these problems are, an year later I just seek something else :D. I hope to find something worthy of sticking to for a bit longer.
