Congradulations:
I've stopped keeping track of all the commuting miles long ago. When you stop keeping track of all the miles, that's when bike commuting becomes second nature like flushing the toilet. Well. I guess I could have used a better example but that was the only thing in my mind.
On a separate note, there are bikers on this forum who have decade under their belt so you have a long way to catch up!
Welcome to the addiction.
