# What You Don't Know You Don't Know

By Roy Osherove October 21, 2011

**Historical article** · Originally published October 21, 2011; technical details may be outdated.

I recently did a talk to a your crowd of israeli developers (it was in hebrew) about a stopic I’ve never spoken about before in a talk - The reasons for my leaving the .NET world for a year. You can see [the video of this talk (and the q&a to follow) in this video](https://osherove.com/videos/2011/10/19/what-you-dont-know-you-dont-know-hebrew.html).

It’s about getting out of your comfort zone, and learning things you never thought existed.
