One of the best topics for new speakers is "here's what I learned when I built project X".

Nobody else in the world could give that talk, because they didn't build that project.

It doesn't matter if you're not presenting anything that's ground breaking and new - what's important is that your audience gets to benefit from the same lessons that you learned.

Even if some members of the audience already knew those lessons, hearing a new way of explaining them - with new supporting stories - is still valuable.
