Once, at school, last year, we had to present a C# project that, upon clicking a button, took words from a .txt file and showed them in an alphabetical listBox...

Since the file they gave us was so long that we had to wait a minute or so to get the listBox full, I implemented a progressBar which popped up on the button, and upon clicking it, the progressBar advanced for every word it loaded, until, upon finishing, it would have disappear leaving again the button, and the listBox would have been loaded.

Apparently, this choice alone – even if it had next to nothing to do with the exercise – was enough to give me a solid 9 out of 10, because our professors never explained us about progressBars and I used that completely on my own... I tend to do things like this in class, where I explore what my tools could give me.

So long story short, I ended up having the best vote in class for that, and I was so happy and motivated :D

Moral of the story: if you can, always try to learn something new about your tools and your programming language, on your own, because apparently it gives you advantage towards others, at least in school. Or even if you're not in school, it could still be something cool to learn that might be helpful in the future, for your projects or your job's projects.
The more you know, the better!
