From doom to boom, this is me

I was this no-one in my office. If i go to office or miss me, no one cared less. Then i came across JN0-422 certification exam. I practiced hard for it and was able to pass it with the help of JNCIS DevOps practice tests at very first attempt. I did not know how far i had come. I applied for promotion and role responsibility in my office and got appraisal soon. Now, people respect me and that i like a lot.
