expertise

There is a theory that you need 10000 hours to become a world class expert in something. And that's not just doing it for that time, it requires that time to be spend on deliberate practice.

I spend around 15 minutes writing these posts. I do try to pay attention to my writing, constantly trying to improve. So I could could count it as deliberate practice. 

Despite my years of experience, I'm still far from the said expertise. At this rate I would need to stack up 40000 posts to reach that. One post per day I'd need to keep doing this another 106 years.
