I don't create my own puzzles that often and when I do I'm often disappointed that I can't come up with something better. But I did come up with this one that's not too bad.
White to play.

There are good things and bad things about this puzzle. In its favor, there is only one correct solution, and it's not completely obvious. Strong players will probably find it easy, but at least it's not completely obvious to anyone and everyone.
However there are several things wrong with it as a puzzle. White starts out with more material, so even if he doesn't find the winning move he's still equal with many other moves. There aren't really any tempting alternatives to the correct answer--moves that look like they win, but don't--which reduces the number of possible lines of play the solver needs to consider.
Aesthetically the puzzle is not particularly interesting. It's a plausible enough position that could arise in a real game, but there's nothing unusual about it that would make you remember it or admire it for its beauty or counterintuitive answer.
Making a really good puzzle is hard, which is probably why some instructors encourage you to create one every now and then. I'm impressed by good problem composers and wish I was better at it, just not as much as I wish I was a better player in general.
