Haha, well, welcome to the club. I suspect we all have these experiences. Most simply won't admit it.
As the sign in the test and repair line at one of my techie jobs said:
"No problem is too big to be overlooked"
Plus it is pretty easy to either make the same mistake repeatedly or miss the obvious several times.
Anyway, if you learned from it I say all is good.
Cheers.
