Post the moments you felt smart by doing something - creating something.
Here is mine.
I always use earbuds, both on my phone and my laptop, so I was listening to music today and I couldn't hear anything, or it was just coming from the left ear. It was broke, I had old earbuds in my drawer that had it's buds all torn apart, so I took the perfectly fine (even better quality than the broken earbuds) earbuds which had just the plastic damaged (I couldn't wear it because the plastic was torn apart), I replaced the broken earbuds' plastic with the fine one, I am using these now, I feel so smart.
