Biggest hurdle overcame in development career - is to work with morons and not fighting with them.

Before you judge me, let me explain a bit. I had the pleasure of working with a lot of really nice and intelligent people in this industry. But along with them, unfortunately, I also have experience in working with really slow and stupid people. For instance I had people in my past who has asked me to create document on how to ssh from a Linux machine or create a bucket in AWS or gcp.

In my early days, I used to get irritated a lot but now I am moron resistant and does not react very quickly on their stupidity.
